Deadline.com reports that Paramount is pretty excited about the performance so far:
This doesn't happen that often, so I don't blame Paramount for crowing about its freakishly good numbers for Paranormal Activity, which will do $500K this weekend on 33 screens playing ONLY after midnight. That's a $15K screen average for midnight business. Yikes! It did $150K Thursday and took in another $200K on Friday after selling out every theater.
Paranormal Activity has been getting scary good reviews, with a 93% fresh rating on Rotten Tomatoes and critics saying things like "Paranormal Activity takes all of the things that go bump in the night and gives you enough of a reason to think they might be real."
Okay, that quote was from our own Sci Fi Wire review, but other critics like it too.
