In GHOST CREW, the titular paranormal investigators venture into the ruins of a burned out hospital, in search of clues about an odd girl who wandered into one of their shots. They quickly decide that the hospital is the perfect location for their next episode.
This is an ultra-low budget, mostly "found footage" horror film. It's an extremely slow-building story, but it's helped along by some spurts of humor, and by having a fairly large cast of characters. In spite of the silliness, the final third of the movie gets a bit more frightening, and a lot more fun.
Although the "big twist" is sort of telegraphed from the very beginning, it's still handled well enough to be acceptable.
Not a bad way to spend a creepy movie night...
