Favorite "Bad" Movies

We all have soft spots for movies that are otherwise not considered "good," "valuable," or that are critically or commercially panned. For some reason, something about the movie speaks to us, or it reminds us of a certain point in our lives, or for some other reason we just make a connection to it.

Some of my favorite bad movies are:

• Brewster's Millions: Fairly standard story of a man who offers his offspring a small sum of money in his will-- or a much, much larger sum if it he can spend all of the original amount in X number of days. The twist here is that the old rich white guy is giving the money to Richard Pryor. Pryor had better movies, but I just get a kick out of this one. I love some of the decisions Brewster makes in how he spends the money and the earnestness with which everyone plays their role. John Candy is very good in a smaller role here, as well.
• The Replacements: I'm not a huge fan of Keanu Reeves or most sports films. Both of them tend to be trite and simple. However, I simply like this film. It is a fictionalized retelling of the strike season in the NFL, with Reeves being a never-was college QB who proves capable of taking a bunch of rapscallions to the playoffs and turning them into a team.
• The Saint: Movie version of the TV show of a Bond-like super thief who uses disguises and subterfuge to get what he wants. This one stars Val Kilmer in a role I thought he was perfect for; engaging, used his talents as an actor, and showed very good chemistry with Elizabeth Shue. I think this one would have done much better had it been released at a different time.
• Groundhog Day: I'm not a fan of Bill Murray or Andy McDowell, but both hit just the right notes in this movie about a guy who lives the same day over and over.
  

These are just a few of my favorite "bad" movies. I have many others that I like and watch nearly any time they are on TV but which didn't have good box office or receive critical praise.
