  1. I still can’t figure out how homegirl didn’t realize her reflection didn’t move when she did. How did she not notice her reflection still in the mirror?

  2. I totally agree with their pick for number 1!! I still can’t watch Peter Jackson’s King Kong without wanting to fast forward through that bug scene!

  3. Whoa those were scary. But that one in King Kong where he’s wrestling those giant cockroaches…..ugh Thats the scariest. Hate cockroaches! That Mirrors one was pretty scary as well. I know my sis told me watching that would make you paranoid of mirrors, she wasn’t lying alright. Imagine if I watched it. Probably will cuz I am a daredevil and a brave boi

  4. The overuse of CGI in the IT remake is one of the reasons I didn’t care for it. All that studdering towards the camera etc. The movie was still pretty good. But Wayyy to much CGI.
