I went in not expecting very much, but I was greatly surprised. The writing was tight (it did not try to do too much), and the execution was very good with great efforts from the entire cast. Despite the "claustrophobic" elevator scenes, the film kept you engaged throughout. I really recommend this film for late night Saturday viewing because it hits all the notes, and does not go OVER-THE-TOP with gore like most low-budget films. In a nutshell "VERY NICELY DONE"!!!
