Ok ok, so I this thing that when an anime becomes to popular I end up not liking it. Hate is a very deep word so maybe not hate but not like. This happens for Anime or anime characters, some even movies.
So my biggest example would be Sword Art Online, when the anime first came out I really really loved the concept of it (I was like how most fanboys would react right now), everytime a new episode is up I always watched it right away. Though there were some parts that I didn't liked but in end overall I liked. I liked it so mich I even watched the OVA. Then before GGO came it was like super popular. If you search the mist watch animes the big 5 is there followed by SAO, SnK,death note, code geass, Full Metal, etc... The pont is SAO is there. Then season 2 came up and well you cpuld say I almost didn't watch ( thank god I did, Sinon is just so awesome followed by Yuuki wow) but still it being "too popular" made me not like it. I don't hate it I just don't like it just bec it became too popular. *ehem ehem* I really really like Sinon though, well.... She isn't that popular hahahaha, Asuna is still the top SAO female character in the light novel so yeah.
Another example is Mikasa Ackerman, I really love her before, she was even in my top 10 favorite anime character but then again became too popular I can't even say I like her as a character now. Same with Levi.
I still like, Bleach, Naruto and Fairy Tail though. I can't explain why I feel that way, maybe because since they are 3 of the big 5 it doesn't bother me?
Again I don't hate SAO or Shingeki but I just don't like them anymore despite loving them before. But I'll still watch both of them again if given the chance.
I only used SAO and SnK as an example cause I feel it is the two most talked about anime. I didn't used Tokyo Ghoul cause I honestly didn't like the second season and that is not because it is popular.
What worries me is this though. Misaka Mikoto for To Aru series is opmy one time favorite character but she is becoming popular slowly and I'm really really happy for that. She ranked best female charcter in Kono ga Light Novel Sugoi ga for 5 straight years, from 2009-2014 only to rank second in 2015(beaten from someone from Oregainu) then ranked top again in 2016. So my problem with this is that I might liking her being too popular and all but I want her to rank first every year. Hahahaha I doubt I'll ever not like her though.
To sum it up all I'm asking is that is it normal to not like an anime/anime character just cause they became too popular?
