Right, so giving full marks to what could be described as a flawed movie might seem a bit silly. Truth is, that's one of the things that make this movie so cool: it's so ridiculously over-the-top crazy and badass that it transcends pretty much all its flaws. The whole point of the movie is to melt your face off, and it succeeds brilliantly. Why penalize it for small details like lack of depth? :)
Action scenes (and in fact movies) have never been done like this. Period. It's pioneering in that respect, and a perfect blend of comic books and motion pictures, in a way that hasn't been explored by graphic novel affairs like Sin City and 300. I guess Zombieland came a bit close with its motion graphics integrated into the environment, but this goes a couple of steps further, fully integrating graphics, swoops, shapes, shaking, and a bevy of other elements into the frame. Add to that Wright's trademark frenetic (but brilliantly followable) editing and storytelling style, and this is one of the most bafflingly enjoyable films of the year, and probably the first proper "comic book movie", as opposed to "graphic novel movie" or "movie based on a comic book".
Watch it, pick your jaw off the floor, and watch it again. A future cult classic.
In a sentence:
Pioneering editing, motion graphics, framing and visual effects techniques take the action scenes to a new level. The rudimentary love plot even manages to appear positively blazing through Edgar Wright's lens.
