Chevy Chase is the ONLY reason this is worth watching
Be honest, this would just be an eminently forgettable bore of a film without CC being the centre of attention in every scene working his repertoire for all its worth.
I'm not saying that I wasn't entertained, I did get a good amount of laughs all due to CC, but the story was really poor and even though they did managed to tie all the threads together by the end, it needed so much exposition.
The plot jumped around so much, from the beach to the country club to the office to a trip to Utah, back to the beach, then the police station, back to the country club, another trip to Utah blah blah blah, by the time it came to confront the character who had taken the hit out on himself I'd forgotten that that was even part of the story!
There is so much about this that is bad that it's a testament to CC that it's still a watchable and reasonably entertaining film. The closest thing I can liken it to as a crime-comedy vehicle for a comic actor is Quick Change with Bill Murray (and coincidentally Geena Davis again), this manages to accommodate a show stealing performance from its lead and be a coherent and interesting story at the same time.
