It's a little too self-consciously stylish -- especially early on -- but it's better to have too much style rather than too little. The heists are fun and the cast is great, so I got what I wanted from it, though I would have loved a stronger ending with a bit more character stuff. Not a big deal.
A horrible (though I suppose unavoidable) ending, but it's a pretty great movie that painted itself into that hole. Fantastic visuals (for the most part) and a smarter take on the zombie apocalypse than I'm used to. I wanted more character stuff and an actual ending, but it was still a good time.
