Stubbornness can be a rabbit hole. You take a stand to start with, and then, without realizing it, you're so far stuck in your own mess, you can't get out.
Vince Vaughn and Jennifer Aniston -- making the most out of two shallow characters -- can relate.
Although she turns him down the first time, they meet at a Cubs game, the two end up dating and after an excessively long montage of pictures of the two together, the movie picks up with the two in a serious relationship, sharing a condo together. Within the first 15 minutes of the film, Brooke, frustrated that Gary can never recognize her needs, calls things off. However, the two fail to discuss their living situation, and as Brooke claims the bedroom to herself, Gary turns the living room into his domain; the two go head on as they each argue to keep the condo themselves.
