There should be a star available for "Oh crap, I bought this."
Given the reviews it received, the cast and the fact that people kept alluding to twists, I purchased it, thinking I would probably want to watch it again in the future. WRONG. Without spoiling it for anyone else, I am just going to say I found it predictable, I don't think that the cast lived up to their potential, and the plot was flat. It felt like an eighties made for tv movie.
What a waste of talent. Wouldn't it be great if you could say, "No thanks, Amazon, I decided I just wanted to rent the darn thing,"? If you are swayed by the great reviews the movie receives here, google it and weigh in with the movie critics for a second opinion.
