Let me list the ways in which this film bites. When you're relying on a few actors to carry the film, you need to make sure you get the casting right. Mistake #1 in a long list with this movie. Neither of the main characters look like they've climbed an indoor climbing wall, let alone a cliff or tower. They'd be better suited to a B grade slasher film. And , if you want us to care at all about the characters then they need some redeeming qualities. Neither do. #2 I've seen better green screen effects on an iPad. The early climbing scene was laughable. #3 The vultures. Maybe this is meant to be a B grade horror. It's getting hard to trust this site when you see such an obvious bomb like this getting 9 & 10 star glowing reviews.
