I also prefer a roleplaying heavy game, and my taste in books tends toward the literary. So that I prefer American cinema seems unlikely to me to be related to a lack of intellectual development, or even to a preference for thoughtless movies.
In fact, if I had to assert that it meant anything, I'd assert quite the contrary.
The Italian film that keeps being mentioned is 'Life is Beautiful', and its ok. As a comedy, the humor must be lost in translation, because I never got it even before the movie took a dark turn. Later, I kept feeling like I was watching Jerry Louis directing a movie about the Holocaust. The movie never quite felt either funny or touching to me, just some weird mixture of both. Like most European cinema, it felt like the guy holding the camera was going 'See, look what I'm doing!' the whole movie, which interferes with my immersion in the story. Sort of like the difference between Kurt Vonnegut and Anthony Burgess. Nobody is going to deny that Kurt is a master of English language, but his continual pretention, irony, literary devices, becomes so tiring that he often seems to be displaying his skill to the literary critics, rather than using his skills to advance a story. For my money Burgess is the better author, though I suppose some people will prefer the fashionable Kurt, because hey, he is fashionable.
