Kirito : ??!?!?!
What will you do!?!? KIRITO !!!! (ノಠ益ಠ)ノ
-grabs popcorn and camera-
This will be good!
"OH GOD NO!!!!"
As for the reason Kirito is OP, it's not just that he didn't need to move a finger to defeat those red players (I'm not sure which ones you're referring to, as if I remember correctly, he had two encounters against different red dudes), he didn't need to move a finger to defeat ANYONE in the show minus a few exceptions. I would like to cite a quote from youtube user Digibro in his video analysis of SAO:
Because Kirito is so ludicrously amazing, it’s hard to feel even a slight amount of tension in any scenario he’s put into. Kirito knows the game better than anyone and is overleveled for every quest he bothers to do, in addition to being the unstoppable lead character anyways. There’s this fucking ridiculous scene in the fourth episode where he gets attacked by seven guys at once and they can’t even fucking scratch him, effectively ending any feeling that Kirito might ever be in danger for the rest of the show.
In episode nine, Kirito makes the baffling decision to hide the fact that he can dual-wield from even his close friends, and allows the deaths of several people before deciding that it’s time to step in and save them. It’s never established why he can’t tell anyone about this power, and he even explains that it’s not something he learned from the beta, but just because it popped up in his skills list at some point. If anyone asked him about it, that’s all he’d have to tell them; and sure enough, once he reveals it to the same friends he was hiding it from, there are no consequences. During his battle with the boss, Kirito had been taken down to low health solely because he hadn’t revealed this power, and as soon as he did, he crushed the boss immediately, proving not only that he didn’t learn his lesson that hiding his powers would get people killed just like it did in episode three, but also that he’s so powerful at this point that he can only even compare to the next-best players in the game if he severely limits himself.
To make a long story short here, the problem with Kirito is that he’s a fourteen year-old boy’s wish-fulfillment empowerment fantasy. He’s the coolest-looking, coolest-acting, most powerful gamer in the history of the world, and every single girl that he runs into falls in love with him immediately.
This OP factor of his doesn't disappear, not even during season 2. When he did that training exercise during Phantom Bullet (you know, the one with the robot cowboy dude) which was supposed to be difficult as hell, he beat it perfectly on his first try. Then there's the vehicles, which were supposedly so difficult to use that few people bothered to try and use them. Once again, Kirito pulls it off perfectly on the first try. His explanation? "I used to play a lot of racing games before". By his logic, I should be able to ride a jet ski like a boss because when I was a kid I was really into Wave Race.
For more information, watch Digibro's video: www.youtube.com/watch?v=3uON7A…
He only used this once though, so it's likely it can't be used all the time. When it comes to reflexes, you really have to stick with me here. Good reflexes are extremely important in nearly every game. If you got just as good reflexes as Kirito, you may become: The first guy to beat that robot cowboy. The first to get dual swords. The best player on the server. A player with such a high level that you will be imposible to beat by noobs. The guy who defeated a boss alone and the guy that react fast enough to cut the bullets in half if someone shoot at you. WITH A SWORD! May the force be with you BTW.
When it comes to those other things you said, you may recall that after the battle with GE, Kirito told his closest friends why he couldn't use the dual sword skill. AND WHY AREN'T YOU GOOD AT JET SKI?! Well because:
A: Wave Race is NOTHING compared to a NerveGear Jet Ski game. Keep that in mind.
B: Kirito have the same vehicle in real life. Check it out!
Not only is Kirito OP, he is so OP that everyone else in the show is made inferior by comparison, including Asuna, who throughout the Aincrad arc is established to be stronger than Kirito. In the episode where Kuradeel paralyzes Kirito and tries to murder him, Asuna shows up and fends Kuradeel off, only to get overpowered and rescued by Kirito, who broke free from the paralysis through sheer force of will. There is, of course, the possibility that he had an item that could've cured him from that status condition, but the paralysis was supposed to keep him from moving altogether, so I can't imagine him being able to move his arm to pull it out or select the option to use it or anything.
Moreover, earlier in the show when Kuradeel tries to make Asuna go back to the guild, she hides behind Kirito and he challenges Kuradeel to a duel with Asuna's freedom on the line. Why? She's supposed to be stronger than Kirito and perfectly capable of fighting her own battles and defending her honor. But no, Kirito has to be the big man and make the decisions for her. Not only that, apparently in the original Light Novel, Asuna is the one who kills Kuradeel and saves the day when he tries to kill Kirito. But the show just had to put Kirito on a pedestal by having him do something impossible for a regular human being.
As for the dual wielding thing... I don't see how telling them beforehand that he had this ability but didn't know how to unlock it would've caused any problems. His friends didn't get mad at him after he told them, and it's not like them knowing beforehand would have in any way affected the fight against GE. And it would've been more satisfying to see shots of him training or trying to master dual wielding in previous episodes, or at least giving us hints that he was working on it rather than just springing it on us.
Finally, the vehicles. Let's assume for a moment that Kirito isn't the only GGO player with a motorcycle in real life. Are you seriously telling me that all those bikers in rl, who most likely are just as good at riding a motorcycle as Kirito, were completely incapable of riding a vehicle that is claimed to be impossible to handle even though it looks like a bike? And keep in mind that there's no mention of Kirito having played a NerveGear racing game.
Serously. Miracles happens all the time, and do you REALLY belive that Kirito willed himself back to life? You didn't belive in the power of glitches? Belive my friend, belive.
About that paralyze thing with Kuradeel. Here are posibilities for what might have happend:
A: The paralyze effect weared off.
B: Asuna used a HEAL crystal at him. HEAL i say. HEAL. At Kirito.
When it comes to Asuna. Everybody BELIVE she is a badass because of her first impression, but watch the intro to the Aincrad arc one more time. What do you see? A scared girl sitting on the bed. Asuna was scared and hid her feelings. She's no badass for real. It become more and more obvius when we get to know her better throughout the series. Remember Mothers Rosario? Yeah, she isn't a strong person as she seem like.
And dual wielding? Well, he told Liz about it remember? He just wanted to give this information to someone he could trust. Remember that Asuna and Kirito had just become a party, and that Klein and Kirito hadn't the best contact with each other? You don't? Sorry.
And at last, something you never would think makes a debate. The veichels. Well, i'm saying that every singel person from GGO with a real life veichels, would be able to use it. BUT WHAT IS THE ODDS FOR THAT?! There can only be a few GGO players that got that thing, so it must be extremely few that can drive it! Oh, wait...
i will kill you
yui is really serious about that no flirting thing.
Asuna one second later in her prison: KIRITO-KUN (Brings up a sword)
Yui : PAPA! NO cheating on mama!!
