Question: You are considering whether to buy a product. You look at the reviews. Would the following review decrease or increase the chances of you buying the product? Review title: Blah. Product review: I confused this movie with the 2006 release of The Covenant. I still went ahead and watched it, and it was a complete waste of my time. Edward Furlong drives me nuts. There is just something about him, his walk, the way he delivers his lines, that just really bothers me. The plot is prety thin and the acting isn't that great.If you're desperate for a movie then I would consider it, otherwise, don't waste your time on it. I'm usually pretty lenient with movies, especially B movies, but this one is definitely not a "winner" in any respect.
