Given that premise and the stars attached you have the makings of a classic comedy.  As with many things in life, all is not as it seems.  Relationships are complicated, whether it be between a man and wife or two best friends.  You can look at the movie and think “Well, of course, Winona Ryder’s character would cheat on Kevin James.  She’s hot and he’s fat.”  Shame on you for thinking in such broad terms!  No, there are bigger, more complex reasons behind the affair and the movie opens up a whole can of moral worms. 

Ron Howard, given his background, has a reputation of being a fantastic actor’s director.  While Vince Vaughn and Kevin James sometimes fall back on their old shtick, they have some moments in this movie where they have not gone to before as actors.  This movie can also be considered an “I’M BACK” message to all of Hollywood from Winona Ryder.  She has already grabbed some attention from her supporting role in “Black Swan”, but she really shows why she was an Academy Award nominated actress back in the 90s with her portrayal of Geneva.

If this movie was made to be a drama with some funny moments in it, we may have had a fantastic movie on our hands.  Instead the movie focuses on its many silly moments that try to get laughs, but earns very few.  The movie never feels right.  It is rated PG-13 for thematic elements and language.
