I'm a complete and utter sucker for these types of movies which (without delving into spoilers) not only play with a paranormal/supernatural concept in such a way as to be explained by something mundane, but also leave the mystery intact by not fully explaining everything to us, and framing the story in such a way that it could easily be either one or the other.
This film has a bit of a goofy start, very plainly obviously low budget and some of the acting drops to some questionable quality. This is not the major problem, but the style of the film doesn't do much to try to overcome this low-budget feel, and so a lot depends on the viewer being able to latch on to the characters, Eric and Beth, to navigate them through the early parts of the film which play coy with the concept ---- Eric is studying "modern mythology" and leans heavily towards being a skeptic with regards to alien abductions, and has to be dragged into that realm of possibility in more and more convenient ways.
The film has something of a twist ending, but the best part about it is that the twist ending isn't something that comes out of seemingly nowhere or requires you to have been taking notes all throughout the film; the inevitability of it is very slowly and gradually brought up all throughout the last 30-40 minutes of it.
Even the most casual of viewer can start to pick upon the idea that a whole lot of the conflict and conversation, even down to mundane events like Eric's former professor paying him a visit the day after a call in which he expressed interest in returning to school to work on his doctorate, starts to become more and more easily ascribed to paranoia rather than aliens.
and yet when the ending hits, it does so in a way which does not nail down one resolution over another, but instead escalates the conflict in a much more complicated way, in which it becomes even less clear what the truth really is, not because the case for either explanation is flimsy, but because the seed of doubt can completely break down either one.
