Zombieland is really good as zombie comedies go. I thought the "Rules for Surviving Zombieland" gimmick was used pretty cleverly, even if the concept wasn't totally fleshed out. It's not as funny as Shaun of the Dead, but, as dachelle said, it doesn't have Simon Pegg, Nick Frost, and Dylan Moran, so how could it be? It has a different sense of humor and tone, and I thought it was more successful at blending drama and comedy. The dramatic emotional moments in Shaun of the Dead felt out of place and took me out of the movie a little because most of the movie is so broad, but Zombieland was unexpectedly affecting at times. You really get to care about the characters since it's a very simple, stripped-down narrative: four people try to survive after the zombie apocalypse. That's the story. So it has to be about the characters.
Jesse Eisenberg is like a taller Michael Cera, and since he's romancing the (Emma) Stone, it's sort of like Superbad with 100% more zombies and 300% less Jonah Hill. Woody Harrelson has a very good time. And, man, I am really liking Abigail Breslin. She's so much more entertaining and natural than other child stars and less weird-looking than Dakota Fanning. She was great in Little Miss Sunshine, of course, and I also liked her in Push. How old is she now? IMDb says 13. Also, that was Dakota Fanning in Push. Motherfuck! I cannot keep my precocious child stars straight. Anyway, keep on snarking, Abby. Oh, she was also in Definitely, Maybe! She was adorable in that. But she's more fun in Zombieland.
Anyway, I don't agree with said cute girl—there are actually two cute girls at my comic book store: one is prettier but this one has a more appealing personality—that Zombieland is basically the pinnacle of zombie movies and no one can make another zombie movie now. It's a good, solid flick, but it didn't blow me away or anything. I am glad it did well and pleased that there is already sequel talk, but I am more pleased to learn that Zombieland was actually envisioned as a TV series, which means they already have more stories they were intending to tell and wouldn't just be pulling sequels out of their asses.
Go see Zombieland! It is approved by erstwhile medical writers and cute girls at comic book stores worldwide!
