I Am Legend was a bore.
i loved 28 Days Later. the second one - not so much.
Resident Evil series is great. all the new Romero remakes are great.
Quarantine was fun. i've yet to see the original (REC)
Zombieland - oh yeah! really enjoyed that, it had some good energy.
Left4Dead 2 is a blast. decapitating flaming zombies with a chainsaw is quite entertaining.
zombies are great, but really i'm a fan of the whole "survival fiction" genre. Mist, Cloverfield, Tremors, Pitch Black - yeah
