Damn you Ashton...even in hell you are a douche bag! How dumb do you seriously think we are. We know you did this same exact movie plot in Just Married. Everyone knows how this one ends too. If you are unsure of the emotions you will be feeling I will express them to you in words.
Start...funny, funny.
5 minutes in...crappy, crappy.
Middle till about 5 minutes to the end...crappy, crappy.
End...happy.
So to sum it up there is about ten minutes of happiness in this movie. Save yourself the anguish and watch The View.
