Students suspect that their teachers are aliens after bizarre occurrences.

This is very much a film of the 1990s, especially the second half. That same teen horror subgenre that "Scream" mastered and "Disturbing Behavior" did well. Get a mix of teen idols, add a soundtrack, and boom, you have a film. This is no exception, with some of the biggest names of the time on the screen (now, about fifteen years later, it is interesting to see who is big and who is forgotten).

As far as being a "body snatcher" movie, it is pretty good. It is obviously aware of its past, as it overtly makes reference. But it also tries to steer clear of being a copy. Some references to past films are over the top, such as naming a character Edward Furlong. Really? Although not one of Robert Rodriguez's best films, it is still a nice trip down nostalgia lane. And it is probably not his worst (it may be time to stop with the "Spy Kids" and "Machete" sequels).
