Wanted to like this movie because I like Gene Wilder a lot. But it makes it hard to relate when you see how nice and likeable his wife and kids are... and the lengths gene wilder goes to to cheat on her. Its really hard to like his character and all of the men in the movie.. they just cheat to cheat and have no redeeming qualities or valid reasons (mean/disloyal wives, etc) to cheat. You need some redeeming qualities to be a likeable character IMO.
Another flaw with the movie is the plot is jumpy and all over the place.. a bit random at times. I'm also not buying that a supermodel would be interested in the main character. Plus the jokes aren't funny, there's very little chemistry between the characters.
