Full review on my blog max4movies: 41 is an independent science fiction movie about a student of philosophy, who discovers a trap door in a motel room that leads to the past. The premise is basic but interesting, and the movie is mostly well executed, with great cinematography and an atmospheric score. The performances are somewhat middling, but the main actor mostly does a decent job. The plot is overall thrilling and clever, however, the ending will throw some viewers off, due to a central plot hole. Still, the movie is efficiently made and demonstrates that science fiction can also deal with very down-to-earth issues.
