Another cliché switch-bodies movie with a slightly different dialog and different actors. I personally favored Ryan Reynolds in this movie; he played a great irresponsible dummy or so. Whereas Jason Bateman always has the same characteristics in all the roles he plays; but it works. The different lifestyles of the friends works well for this movie as did "It's A Boy Girl Thing" with mixing the sexes. The best part is understanding what the person who switched lives with you actually has to deal with in life; it's another hard lesson in life, but necessary for stubborn humans who only see themselves. It's a great lesson for movies, it's just been done so many times before. This movie is worth watching because of its creativity.
