I believe some people expect entirely too much from some movies. A viewer should expect nothing from a movie and allow it a fair chance to show you what it's all about. Otherwise, feel free to be pissed that The Exorcism of Emily Rose turned out to be a crime drama and not the ghost story you were hoping for. That's merely what you assumed the movie would be and now you're mad because it failed to match your false assumptions! And we all know what happens when we assume.
I expected nothing more than 90 minutes of entertainment when walking into the theater to watch Slither. The preview piqued my curiosity, being a huge fan of the horror genre, and I was also intrigued to catch Nathan Fillion's first non-Firefly role. I learned a long time ago to ignore the rants from the stuffy critics as well as raves from drooling fan boys, since I often disagree with both, and simply sat down and gave a simple horror film its opportunity to entertain and amuse. Slither did both.
Synopsis: Alien slugs begin mutating and zombifying Small Town, USA.
Michael Rooker plays the wealthy Grant who is hated by everyone in town, save for his wife. Grant and the missus have a bit of a falling out one night and he storms out on his own. In the woods, Grant encounters a strange, slug-like creature, feels the uncontrollable need to poke it with a stick, is subsequently injected with a parasite, and begins undergoing a series of transformations.
Mrs. Grant notices his strange behavior over the next couple of days and turns to her old flame for help. That old flame is now the town sheriff, played by one Nathan Fillion, who dismisses her concerns; until he sees exactly what Grant has become, that is. Now it's up to him to figure out exactly how to deal with this monster.
