Not going to win any awards, but take it as it is: a popcorn movie with some funny lines and some bizarre situations.
John Candy can almost do no wrong in a movie, though Eugene Levy's acting could've been stronger. The pair, oddly enough, play off against each other and it works.
The premise itself has merit and I can't go into detail without spoiling it, but I could see something like that happening in real life. Meg Ryan's character shows some strong development, but she fell a little too easily for Levy.
This movie does have one of my favorite lines of all time: This is a .50 caliber. They used to use it to hunt buffalo, up close. It's only legal in two states. This isn't one of them.
Final thought: Ice Cream Man.
