Sure, most of the time it's fractured, clumsy, even jerky. But what it's got going for it is that it's relentless. It pushes forward at breakneck speed and that really compensates for everything else. It's what makes it exciting and a great watch. It looks good too, there's this modern feel to it like you're watching the near future, even though it's nine years old at the time of writing this. The actors (and the characters) are very likeable and charismatic, not one exception among them. A surprising movie all in all.
