“Monster On A Plane” (*1/2 out of four) was a third-rate horror comedy about an exotic animal that turns into a monster aboard a plane and wreaks havoc for all the passengers (Eva Habermann, Robin Czerny, Nicholas Artajo, and others) who just want to enjoy the flight and join the mile-high club. Obviously inspired by “Snakes On A Plane” right down to its title but there’s no great lines like “time to get these snakes off this muthaphu–in plane”, no Samuel L. Jackson, and not much else to keep you involved. Monster here looks like a leftover from “Critters.”
