I am not usually a fan of Ben Stiller films (bar 'Meet the Parents') but Along Came Polly is an exception! The storyline is nothing special, Stiller plays Ruben Pfeffer - a risk assessment analyst, whose world collapses when his wife leaves him on their honeymoon for a scuba-diving French nudist. Ruben then bumps into an old schoolfriend, Polly Prince (played by Aniston)a commitment-phobic, indecisive free spirit, whom he eventually falls for. The road to happiness is by no means straightforward for Ruben, and the situation isn't helped by his interfering mother, and some seriously inappropriate advice on dating from his best friend, and ex-child movie star Sandy Lyle (played by the sublimely talented Philip Seymour Hoffman).
The storyline is definitely not the strong point of the film, but the cringeworthy situations of the characters are hilarious, and if you are the type of person that can relate to that sort of humour then you are going to love this film. From Ruben's interfering mother, his wife Lisa making him feel guilty for her own infedelity, to Sandy's performance in an amateur dramatics revival of Jesus Christ Superstar - these are all really cringeworthy moments, and you feel embarrassed for the characters at the humilation they are often subjected to, maybe because they happen in reality.
The key to enjoying this film is being able to appreciate indirect humour, the laughs are found within the helplessness of the character's predicament rather than slapstick silliness. I can only compare it to the British series "I'm Alan Patridge" - it's an acquired taste, but if you can grasp the humour, it's a real winner!
