i saw movies whit running and swimming zombies.
28 Days/Weeks Later? Those weren't really zombies, it was more like an advanced version of rabies. They'd get very angry and want to kill anything. They didn't die and come back to life or anything.
Zombies like in the first and second RE movies (even the Dawn of the Dead remake did a fine job with zombies) and the early games is what I'd like to keep on seeing. Bring back the scare and deep plot factors instead of making it all about action.
