It would be easier to like Poolhall Junkies – a serviceable rehash of every other billiards movie ever made, courtesy of writer-director-star Mars Callahan – if Callahan didn’t like himself so much.

Narcissism is a necessary trait in a movie star, let alone a star-auteur, but even a narcissist should leave room for other admirers.
