Why are some people so personally invested in their favorite television shows?

I can understand really getting into a show, and waiting with baited breath to see what happens to your favorite characters each and every week. (I’m like that with Battlestar Galactica and Lost.) However, I’m not so obsessed with a show that I get pissed off if other people dismiss or even insult it. If they don’t want to watch it, then who cares?

I’ve literally been yelled at and insulted over stuff like this, even if I merely stated that I wasn’t interested in a particular program. Granted, I’ve gone out on a limb sometimes and said that “[insert media here] sucks,” but I won’t attack someone personally based on what they do or do not like. So why am I getting bitched at in return? It’s not like these people are in the show in question. Nor do they own stock in it. Perhaps they just need a new hobby.

The same applies to films and music. I’ve seen people flip the fuck out when I’ve expressed disinterest or distaste with certain movies or bands. Seriously, relax, and lower your goddamn blood pressure.
