Yes I agree - and in fact I do with some movies. I also learn a
   lot about a persons outlook on life based upon the movies that
   inspire them. But I also judge and stereotype quickly - the feel
   of a movie or subgenre almost becomes more important to me than
   themes. The reason for me is movies generally have common themes
   that are easily compressible by "feel". A sarcastic bloody movie
   where death is funny, people aren't particularly nice to one
   another - this "feel" of a movie take away from me an interest
   in studying it further. There are likely many interesting things
   about them. But if I get a feel for a movie that the good guys
   are jerks, the bad guys are jerks and the redeeming character
   traits are something in the subtext... Well anyway that's my
   prejudice.
