Needed a better Director
Really not a fan of the director or his style of humour, very basic and childish his film are just not funny and don't really work. I don't think he has ever heard of subtle or deapan humour.
Steve Martin tried his best, but he needed more help by somone with better comic direction like John Landis, with more advanced comic skills. I doubt it would of been great but at least there could of been some laughs.
