If you're a fan of The Twilight Zone then this will be right up your alley. So what that we're not told where the doors came from or what their purposes are - you're left to make your own assumptions and the ominous sounding "Time to Refresh" gives the movie a Matrix vibe but you decide... I'm glad I decided to watch despite the poor reviews. If you're not a Sci-Fi fan then walk away - this movie doesn't deserve any more bad reviews.
