Oh cool are you a fan of SDF Macross and/or the DYRL movie? I know you don't like dubs but I do love the uncut ADV English dub version of the TV series (aka the one that's not Robotech), it made it one of my fave anime I got really into it and I've watched the whole show at least 2-3 times now. I acknowledge the animation quality is, uh, variable, and that might put some people off but I really enjoyed it and am keen to rewatch it again at some point in the next couple of years
To keep this thread on topic, I'm trying to think what anime I dropped due to not liking one or more of the principal cast members...
I did watch all of Death Note but didn't like Light (not trying to start a fight that's just my opinion), I have been put off a fair few modern isekai by some of the male MCs being...
makes the face the fairies make in Soul Eater when Excalibur is mentioned... even tho I loved Excalibur and found him hilarious Not all of them just some of them, and I actually like some well enough that are divisive like Subaru from Re:Zero (he's not my fave MC ever or anything but he def doesn't make me wanna drop the series).
I can see why some of the other characters and series here have been mentioned:
Taiga is far too angry and violent for me to really
love her as a character, I still enjoyed Toradora and I did appreciate that they did try to make her and some of the other characters a bit more complex than just them being super nice great people all the time (even though I tend to respond well to super nice great people lol)... but when she gives Ryuji a threatening look about halfway through just for finding another girl attractive or having some sort of possibly sexual thought all I could think was "if I had a boyfriend who treated me the way she is treating him, I would dump his scary jealous ass" so yes she at least can sometimes be an absolutely terrible person and she's def one of those characters that only even half "works" in a cartoon as if it were a live-action show she would be a domestic abuser.
I didn't really care for Macross Plus, even though it's the kind of thing that on paper would be right up my alley - I didn't exactly drop it, but I've never actually finished it.
Didn't mind S1 of Love Chuunibyo but it's not one of KyoAni's best for sure.
I can see why Irresponsible Captain Tylor would be divisive but I find the show great fun and the character mostly endearing and cute.
I like Shirou Emiya, I appreciate his kindness and sincerity, based on having watched many of the Ufotable Fate entries (Zero, Unlimited Blade Works and the Heaven's Feel films), I think he's a nice young man.
I get why the Tsubasa Reservoir Chronicle anime would appeal less to someone than MKR or CCS, there is something about the pacing that is just so slooooowwww.
I didn't finish Attack on Titan but that wasn't especially due to Eren.
