Movies like Dawn of the dead and Resident evil are always good popcorn entertainment. But nowadays things are getting downhill.
And so is games like Dead Rising, where you can kill zombies in creative ways.
But
Sankarea takes the price. It's an great anime, if you haven't watched it yet please do, you won't be disappointed.
To answer the question, It's not the best sub-genre, but it's very enjoyable to see zombies get killed.
I'm off to see Dawn of the dead (1978).
