(Film Critique). When a movie starts out engaging and has great potential, but then the ending falls apart and the whole thing turns to shit. It's like finding an Upper Decker when you flush your toilet at the end of a party. It's there, and it's shit, you just don't know it yet.
The movie Enemy (2013) was a real Upper Decker.
