I think the main question you asked was "Does liking stuff that is below you make you unimportant/stupid?"
Not really. I find some of the dumbest stuff funny, like I love to read reviews on spam even though it seems stupid to laugh at people getting pissed off.
But what about times where a bunch of kids get together and make funny noises. (Like in my most recent animation, in the scene where it shows the outside of our SPace Helicoptor) Is it stupid to find something like that funny? Not really. It's just whatever manages to make you laugh. I can laugh at a stupid picture of a cat saying "im in ur printer" or something, but I'm not exactly stupid because of that.
Again, it's just whatever tickles your funny bone (Tickle and bone should never be in the same sentence, btw) and it doesn't make you dumb.
People who like sprites aren't dumb, and people who hate them aren't, they may be ignorant and place stereotypes over everything, but they aren't necessarily stupid.

what, of course what you like defines who you are.
i think it's perfectly justifiable to presume certain things about a person based on what they like - the concept of pop culture has us defining our identities through the stuff we identify with. like, music for example: if i like my chemical romance you can presume things about me that you wouldn't if i listened to only Rachmaninov.
and while liking some movies might not make you STUPID or 'unintelligent', it does indicate that. obviously your taste in comedy isn't the sole contributing factor but its a pretty obvious signpost to your development.
