I've watched some movies many times. For example, Jackie Brown by Quentin Tarantino. Each time I see something different, whether that's in the acting or in the staging, there's always something new for my eyes or ears to latch on to. Perhaps this should not be surprising given the countless hours people spend looking at a single painting, their minds constantly making new connections to a static object.
A movie, after all, is just one static frame after another but throw in the personas of the actors, music and screenplay and what you have is a much more complex experience. No surprise then that I should find some movies seemingly endlessly fascinating. As a viewer, I really stand no chance but to be overwhelmed by a near infinite amount of possible experiences and reactions.
