Less of an intellectual mind-bender than it lets on
Pi has been placed in the category of a thriller and a mind-bender. Between the teaser poster, the description of the movie and the first few minutes, there's an impression that it's more cryptic than it actually is.

Perhaps the best thing Pi has going for it is the stylized arthouse directing which conveys delirium, confusion and a host of other emotions very well
