“Destined to be together but indecisive and unable to pull the trigger for 20 years” is not my idea of an engrossing concept. It’s my idea, actually, of a repellent one. The narration (“…but life got in the way”) is very cliched, and the British narrator’s speaking style has that same “talking down to idiots” tone that the last trailer had.
So trailer-wise this film has basically gone O for 2 (here‘s my reaction to trailer #1), and in my book that indicates a possible disaster.
