“Alien Trespass” doesn’t intrude enough in the movie territories it occupies.

It’s not funny or kitschy enough for satire and not scary or exciting enough for simulation. The thriller/comedy is meant to both send up, yet also replicate, the sci-fi B-movies of the 1950s. And at least in its precisely simulated midcentury production design, charisma-free cast of D-list stars and intentionally bad acting stylings, it sure looks familiar.
