That's a question I've been asking about myself for like a decade. Like all nerds I consider myself a pretty smart dude but most of the supposed high literature never really worked for me. I make occasional attempt to get into serious novels but it never sticks and I return to my hard sci-fi books.

Maybe it's sheltered nerd life that prevents us from relating to human drama? Maybe being a nerd is being on the autism spectrum just a tiny bit? I dunno.

On the other hand I watch a lot of high-brow movies but more of bizarre surreal kind, less of a "intimate character study of a family going through separation" kind.
