There are tons of anime. Not everything is good or makes sense. It comes down to why are you watching anime. What are you looking to get out of the experience? Why else put the time into it, when there are plenty of other things to do.
That being said there are anime that are extraordinary. Either they have an excellent story, amazing musical score, or terrific animation. If you’re extremely lucky you will get all three.
If you watch enough anime you will find out that there are many titles that will get either dropped, or quickly forgotten. Some anime leave either no impression, or such a bad impression that you will quickly talk others out of watching it if the occasion arises. At times you can get strung along by an anime that has so much potential but lives up to none of it. If you are stubborn you will get dragged along for nothing.
Anime is primarily about preference.
There are plenty of options and genres for you to watch. For example I am a big fan of isekai. But for some isekai is trash. Does that bother me? Nope. I am just going to enjoy watching it anyways. And then to put the nail in the coffin I am going to also write about it on my blog. As they say haters are going to hate. But their hate can’t stop me.
My word of advice for you is to watch what you love. Don’t worry about what others say about your taste. You aren’t living for them.
If your main goal in life is to gate-keep others’ anime choices, don’t be an asshole about it. There is nothing wrong with expressing you don’t like something, or just saying nothing at all. Just don’t overdo it.
