Xavier is right, Jason Bourne does shit perfectly, if you read the books you should know this. The few times he thought he made mistakes they turn out benefiting him in the end. Although Jason Bourne wasn't only very trained but also driven at first by vengance and then by love. Gotta read the books
Seriously, the movies really really suck when compared to the books. Not even exaggerating here, but seriously pick up the first book and if you aren't hooked by the 4th Chapter you have a mental problem or something. They are TOTALLY different from the movies. Honestly, I don't see why they didn't just make the movies more parallel to the books, because even watching the director's cut he admits that the books are very different and a much more powerful story, but his reason for not using them is weak. "Technology has advanced so much that we need to update the Bourne Story". Uhm no dumbass, you need to just make your film take place in the time the story took place and end up with a fucking kickass movie.
In short, go get the fucking books and read them. If you're creaming jeans over these trailers of these movies, then you'll cream jeans at the end of every chapter of the Bourne books, all the way until the end, I guarantee it.
