This is going to be a very short review because, frankly, there isn't much to say about Wrecked. The first 20 to 30 minutes of the film consists of Adrien Brody trapped in a wrecked car deep in the forest
For the remaining 65 minutes, we get to see Brody crawling around the forest / wilderness. Throw in a hallucination here and a mountain lion there, and that's the whole film. Not too entertaining, even with the few appearances of the mountain lion – and that says a lot about the approach director Michael Greenspan took with the film.
Despite Adrien being a great actor and doing his absolute best with the script, the film never really delivers on the suspense or the thrills. It's a one-man show that goes absolutely nowhere, and that's not Brody's fault. Greenspan never picks up the pace of the film; he uses flashbacks and hallucinations ineffectively; and tries to build suspense around a story-line that just doesn't have any.
If you want to see a great survival film with few characters that gets it right, watch Frozen, 127 Hours with James Franco, or the classic Cast Away with Tom Hanks.
