A cult classic B movie that is perhaps the purest example of a B movie, Moontrap isn't a cheesefest of tounge-in-cheek sillyness that happens to be low budget, but rather a relatively serious movie about horrible alien robot things that intend to take over the Earth... which (blog post) happens to have a budget well below what the (blog) vision needs to be realized with the standards we associate with serious films. However, they don't let that get in the way and still present a funny horror movies rather interesting look at a slice of movie history.
