User blog comment:J. Severe/What Makes Twilight So Great?/@comment-3201389-20100412005939

People are going to like stuff you don't. Such is the nature of free will. Twilight is NOT "so great" - for you, obviously, but some people love it. Some people love action flicks, some people hate them. Some hate horror flicks, some love them. I can't stand Harry Potter, but I don't wonder why some people love it. Likewise, the mere thought of intentionally putting slimy fungi in my mouth disgusts me nearly to the point of gagging, but some people put mushrooms on everything - and love them. Variety is the spice of life.

In much the same way that none of us should care what anyone else thinks about our own likes/dislikes/personal choices, so too should none of us waste any effort caring what other people's personal choices are. The more time you spend trying to figure out other people and their actions, the less time you have to focus on your own interests, and everyone loses in that case. You rob yourself of "you time" where you could be enjoying your own pastimes and exploring your own personality, and others feel persecuted by your scrutiny of things that bring them joy.

If we all liked and disliked the same things, we would be nothing more than mindless automatons droning around in a world devoid of individualism. (which would suck.)

A simple answer to your question would be that the "great"ness of Twilight - as with Harry Potter, or anything else - is completely subjective.
