Despite its average budget the picture manages to be intelligent , intriguing and thrilling but also a little bit boring and hard to follow , at times . The good thing about this film is that the director made it on a limited budget only having to do a few sets , yet the movie works on many levels but is constantly reconfigured , though a little claustrophobic .
