It didn’t have any kind of real plot. And 50% of the movie was Kristen Stewart running around in her underwear .. I think it would have been better if they added an extra 30 minutes of story line in the beginning. Some effects were good. The alien creatures were creepy. Honestly I am glad I didn’t pay for the ticket, I had a Gift Certificate. Is it worth watching at home ? Yes but save your movie theater money for something else .
