i should start by admit that i find jennifer aniston adorable . vince vaughn be every fast talk overly confident friend i have ever know . this film could have be great . it isn not . it be a weak film full of odd underdeveloped ( and thus unexplained ) side character and it contain one of the most unsatisfying ( and the big cop out ) ending ever put on film . if i want inadequate and unfunny and unsatisfying and realistic and i will refer to my own struggle relationship . i do not need to pay hollywood top dollar to show me that . i can get that for free . it have it hint at humor and but overall . awful .
