Look. He's certainly opinionated and a bit of a jerk. But there are sooooo many people out there who think their tastes in film and music are like that.

The thing is - they are opinions. We are each entitled to them particularly about what someone decides is good entertainment.

The reasons you said above? Nostalgia and just overlooking the flaws? Those are totally valid things to say to him. I definitely say those things about stuff I like! I'm really good at suspending reality and logic for a story. I can also be very analytical (for example I hate the twilight novels. It's absolutely horrific and I will gladly rant about it. But if someone else likes it, that's cool) but I prefer not to do so for entertainment. I read primarily YA novels, and I was an English major in university and I am now a teacher. Im more than capable of reading very intellectual texts. But I don't because I simply don't want to.

You just need to let your brother know that you're not having a debate about it. If you like something you like it. If you don't you don't. It's ok.
