Not even bad in a good way

Excellent, smart action film.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

From all the hype I expected something worthy of the awards and nominations it has claimed. PI is a well made, well-paced film, always hinting that something significant will be revealed. No, it won't. Some reviewers were impressed by the obsession displayed by the Max character, but I thought it an ordinary day's work for the actor. It certainly is not enough to hold it all together. The one true statement of the movie is spoken by Sol, when he says (paraphrasing), " Once you abandon scientific rigor, you are no longer a mathematician; you're a numerologist." I guess I'm just not interested in numerology.

I love how this film makes you feel frantic. The black and white is darker than usual. The sounds are glaring sometimes. The pace that everything happens, makes you feel insane. This film is a masterpiece and shining star to what indie films can be if pushed to the extreme. One of my favorite films and love the story of the insane mathematician. Beautifully told.

A great soundtrack (Aphex Twin, Clint Mansell) and brilliant cinematography (think Tetsuo The Iron Man) combine to create a claustrophobic and slightly disorienting look into the mind of a mathematician looking for a way to predict the stock market. What Max ends up finding is sought by more than just Wall St and may end up costing him his life.

How do movies like this get a 7.5 rating and cause me to waste 84 minutes of my time? I'm not a mathematician but I know a little about science, I already know about the Fibonacci sequence and how it appears in nature, PI, etc. They just threw a bunch of mathematical clichés and threw it all together into a stupid, irritating mess that made no sense.I was waiting and waiting for something interesting to happen, nothing ever did. The ending was completely ridiculous and unbelievable.What I want to know is how does a movie like this get a 7.5 on IMDb? OK I started out giving it a 1, but in retrospect, since I'm still thinking about it, I'll up it to a 3.Unless you really like artsy movies I'd skip it...
