Tbh. what I love about anime in general is the interesting story lines and how some of them in different variations/seasons of the anime interconnect. It's very exciting to see it happen. I personally chose this because (it's happened before) sometimes anime seasons could be completely different from the last one.
What I hate about anime is when either A: It's sad AF and I cry like WHY WOULD YOU DO THIS TO MEEEE OR B: WHEN ONE OF MY FAVORITE CHARACTERS DIES LIKE OMFG EREN NOOO
