I will always remember the film 'Vacancy' because I went into it with zero expectations and ended up having one of the best film experiences I can remember. Really the only similarity that 'Looking Glass' has to that film is that it was set in a motel in the middle of nowhere. Still though, a part of me had hopes of another hidden gem. It wasn't to be though. The film starts off with some potentially exciting plot points and mysterious goings on, but can never live up to them and provide any pay off.
There's also a serious lack of suspense in the film. At no point are you ever on the edge of your set needing to know what is going to happen next. The film just kind of drifts along and even when something that's supposed to be exciting is happening, it really isn't that captivating. The one bright point for me was Nicolas Cage. Even though his career has been in serious decline for over a decade now, he can still act the pants off most people in the industry when he tries. Sadly though, he's far from enough to save this forgettable film that I wouldn't recommend spending your hard-earned on.
