My daughter saw this last week and thought it was the best of the bunch. 1 did the job and got me pretty good.. I thought 2 plodded along too much and thus, didn't bother with 3.. Maybe I'll have to check it out, now that it's in the dollar theatres.
While we're on the genre, I absolutely had no idea that Apollo 18 came and went without so much as a whisper. I assumed it hadn't been released yet. Geez... Guess it was pretty bad.
