Ah, the Horrorfest movies. Some good, some bad, some really bad, and some much akin to what I imagine getting raped by a bear might be like. Mulberry Street, thankfully, is.... alright.
Mulberry Street is like Quarantine (a remake of the much superior spanish horror film, Rec) except instead of a deadly outbreak of a disease that turns you into a mindless, blood hungry maniac contained within a building, it's contained within the island of Manhattan. Also, instead of this being another 28 Days Later or I Am Legend, these blood hungry disease-ridden people aren't mutating into zombies.... they're becoming rat people. I know, it sounds cheesy and it could definitely have been cheesy, but honestly, it wasn't.
I think the reason they were able to pull this scenerio off successfully was for a variety of reasons. For one reason, the cinematography was fantastic - the film felt gritty, dirty - much like the streets of the city, the film was dark, lights constantly going out and flickering on... off... on... off. The rats that originally bore the virus bit a few initial victims, and from there it spread like wildfire. The survivors in the streets and apartments the story centered on not only had to avoid the rats, but the people who were very quickly mutating into fast, hairless, pointy-toothed ravenous, mindless killers. They had ratlike features - some ran on four legs, some had pointy ears, but they still seemed to maintain a little of the intelligence that they once had. Punching through doors, tearing through ceilings to escape being trapped. They are hungry, they want to eat you, and they are fast.
Another thing I felt probably helped the movie was that it was unhindered by a famous cast or even so much as a familiar face. The movie mostly followed six or seven people who all lived in the same building, although much of the action does take place in the streets and outside the apartment complex. The characters felt real and charming, from the two old men who lived together and bickered tenderly to the main character, a man waiting for his daughter (who had just gotten out of the military) to come home. All of the actors played their parts beautifully, which is very impressive for not just a horror movie, but a movie with a very small budget.
So I'm going to suggest that, if your a zombie fan or a horrorbuff, you check this film out. It's different, it's good, it's worth the money to rent or buy. Or, you know.... download if that's your thing. ;)
