Peter Cotton (Corin Nemec), a scientist, returns to his childhood hometown for a high school reunion during Easter weekend. He meets Anna Banana (Dominique Swain), a girl from school whom he had a crush on, and Jake (William McNamara), who used to bully him. When a bunny rabbit bites Peter, he turns into a half-man, half-rabbit creature known as Rottentail.

      Rottentail is a horror comedy with too few laughs and no scares. Very little makes sense, but it's not supposed to. Describing the plot wouldn't do it any justice. It's very gory, silly, mindless and unabashedly weird which makes it feel very much like a Troma film. The screenplay by Kurt Belcher, David C. Hayes and Kevin Moyers isn't nearly as funny nor campy as B-movies The Toxic Avenger, Zombeavers and Stung. It quickly becomes tedious, dull and repetitive while its comedic and campy beats don't quite land. Perhaps it would be best to watch Rottentail with a large, rowdy crowd at midnight. The crowd experience, though, might become much more entertaining than the film itself. Unfortunately, it never reaches the "so bad, it's good" territory like The Room did, but there have been worse misfires than Rottentail, i.e the painfully unfunny Holmes & Watson.
