This ain't that kind of movie.There is a lot of things right with this movie. One, the villain is not evil. Well, not entirely. His intentions are good. He's not a simple stereotypical caricature as seen in most movies. Die Hard 4 tried something similar, having an antagonist who was trying to 'better' the world - as do so many other movies - but few rarely get it right. This movie does. It honestly does make you think about if you wouldn't support the villain's 'nefarious' plans. I probably might have.
Two, there's a measured restraint in the self-referential humour - something that Scary Movie(s) started to get really wrong. So, did Two And A Half Men. The movie has its moments in its solemn tongue-in-cheek moments where they refer to the overblown theatrical plot. The characters know it and like it. The audience knows it and likes it. 
Three, the fight scenes are brilliantly choreographed. There are three main long fight scenes - each quite different from each other - and yet snazzy. It isn't realistic like Jason Bourne, but then again this movie isn't trying to be Jason Bourne unlike the new James Bond movies - which brings me to my fourth point.
This movie takes you back to what was the essence of James Bond. and similar movies. There's the martini joke, being a gentleman, sex with the beautiful woman after saving the world and the most important of them all - gadgets! Over-the-top but god-how-I-wish-it-was-real gadgets. At the same time it also brings to the table the kind of genre-bending film you expect from Matthew Vaughn (Stardust, Kick-Ass). While abiding closely to the rules of the genre it breaks away from them just enough to not be cliched. "This is where I tell you all about my evil plans," says the villain when he has the super-spy cornered. "And then find a convoluted way to kill you, and you find an even more convoluted way to escape," he continues. "That sounds good to me," says the super-spy. "But, this ain't that kind of movie," says the villain. And kills the super-spy with a bullet to the head. The villain is smart. The movie is smart. You'd be smart to watch it too.
