I have watched a lot of movies over the years; more so than the average viewer. Being a fan I seek out new and obscure content on a daily basis. A day seldom goes by without me watching a movie or at the least a TV show. As I am not a causal viewer, a movie gets my undivided attention. I focus on dialogue, composition, editing and also try to take in the subtle background detail that can often yield some extra level of enjoyment. As a result of my passion, I can often remember minute detail and recollect specifics, long after viewing. I guess this is the nature of fandom. If you like something, you retain it.
