I found one particular film good although it was in black and white, but that just added to it's atmosphere. Pi isn't a quick witted comedy or a light hearted story, it is indepth and will possible make you think. Of course if your not very good at mathematics you might be shuddering at what the "hero" contemplates, and understand that the film consists of the hero's narative as he works his way through his conundrum. Some people might want to walk out through the film, or think they would have spent better time watching some film with explosions in, but this film is meant for people who think rather than just something that can act as background noise. word of warning when you do reach the end of the film, you might not want to follow the hero's footsteps... You might notice, That nothing that I have mentioned to you will in the slightest give the plot away.
