I saw Zombieland two weeks before it came out at a free screening. I give it a solid B in the ZomCom genre.

I prefer Fido , then Shaun of the Dead, but that's a close race.

The same week a movie called Dead Snow a Norwegian ZomCom. It was playing at an arthouse theater here. I liked it more than Zombieland.
Dead Snow
Check it out when it comes out on DVD. If you like the ZomComs, I think you will like it.

Cheers,
