I just finished watching Apollo 18 and I liked it. I thought I was going to love it, but it was ok. The mistake in most alien movies, as I have said before, is that you should never show the aliens. In this movie, though, the aliens were spider-like, so it was a little less CGI-looking. Lots of suspense and the heavy breathing made my asthma act up. LOL
I would give this movie 4 out of 5 stars. If you like government conspiracy theories and “Paranormal Activity” style, this is the movie for you.
