Slither is what it is, unapologetically, and unlike Gunn's work on "Dawn of the Dead," it's probably too weird to be a crossover hit. Either you've got worms in your heart or you don't.

Let's get this straight from the start: Slither isn't great art, but that doesn't mean it isn't good entertainment.
Slither begins briskly, gradually accelerates and eventually achieves a breakneck momentum that makes the wild ride even more exhilarating.

There are times (and plenty of them) when Slither slops over from smart, affectionate homage into unmodulated frat goofiness as Gunn cannibalizes so many horror plots with such high spirits.

While Slither sometimes feels like a monster-mash, what makes it work is how nimbly it slaloms from yucks to yuks, slip-sliding from horror to comedy and back again on its gore-slicked foundation.
It's the kind of movie that used to be called "trashy good fun," only there's nothing trashy about it: Gunn, who scripted the 2004 "Dawn of the Dead" remake, is clearly punch-drunk with horror-movie love; Slither is, among other things, a freewheeling homage to "The Blob, Invasion of the Body Snatchers" and just about everything by George Romero.
Though it occasionally dips too deep into a well of redneck humor, Slither cleverly exploits the nervous laughter that fills a theater whenever a horror movie gets too frightening to bear.
Washington Post by Teresa Wiltz
Slither purports to be a "horror comedy" but in embracing the hybrid, it falls flat, never committing full-out to mining for giggles or gasps.
