Starts off very edgy but gets surprisingly sweet. Lupita Nyong'o is as always perfect and the zombies look great.
I actually hadn't heard of this one from Nolan until I saw it expiring from Netflix. Anyway, it's a decent cop thriller. Hillary Swank is good, Al Pacino turns in a good performance. I always like Robin Williams in roles that kind of blur the lines between good and evil, and he makes a good villain here.
