Hate to say it, but Misha Collins is the only good thing about this movie.

Yes, you have correctly apprehended from the title that this is, in fact, a B-movie. So your expectations are low. Try to squash them down a bit more before you start watching. Judicious alcohol consumption may improve the experience.

If you can lower your expectations sufficiently–start by embracing the other review that says Misha Collins is the only good thing in this movie–you might be pleasantly surprised how much you enjoy it.

Which is not to say it's good, because it isn't good. At all. It makes even less sense than you've come to consider normal for on-screen science fiction. Suspension of disbelief- Not likely. You have to ACCEPT your profound and unshakeable disbelief on this one and keep watching anyway. Good luck! There is definitely a certain pleasure in watching earnest actors TRY SO HARD to make it all ring true when the script is such a preposterous waste of paper. The special features aren't much to write home about, either. But Misha Collins is very watchable.

Try to get it on sale, as you're not likely to watch it more than once.
