The beginning and the end were pretty good - but the ludicrous and far too lengthy subplot in the middle involving their attempt to get Jaime Lee Curtis to confess to having an affair should have been cut completely. It pretty much ruined the film.
That was what made the movie so much fun!
Oh come on! Have a sense of humor! It's not suppose to be 'The Godfather', it's suppose to be a slick action flick with one liners and cool action sequences.
