After reading a few reviews of this cross over indie success - about two friends stuck 2,000 ft up a tower, I have to disagree with most of the criticism. I didn't find it over reliant on hanging off things, too long or injected with melodrama. For the most part this "climbing-horror" plays out like Waiting for Godot in the sky, has a screenplay that builds pretty expertly (rushed end aside) and when the melodrama comes, its given short shift. Fall has enough stare-through-your-fingers height scares, but crucially not too much.two pretty great leads, a reliance on script, is well paced and a stunning visual (symbolic?) location. Top stuff.
