“Zombie Town” (** out of four) was a one-note horror comedy about two friends (Madi Monroe and Marlon Kazadi) who watch an old horror film reel and unearth a horrific curse and have to track down its old filmmaker (Dan Aykyroyd) to save their town from an invasion of zombies and stay alive. Good-natured movie has a few laughs and Aykroyd in perfect casting for good measure but unfortunately the chills and chuckles don’t add up to much. Chevy Chase and Henry Czerny have amusing supporting roles but are otherwise wasted.
