It’s complicated.
JJK current >>> MHA current. And not for a short time.
But for 70% of its course MHA had stronger themes, was a bit more entertaining, good use of the villains, and solid characters like Endeavor, Hawks, Nagant, Twice etc.
I don’t feel JJK characters as much as I feel MHA characters. JJK characters aren’t bad but they are quite 2D. Things happening in JJK without me to be that involved in the characters. JJK characters are cool, and are doing cool stuff and I don’t ask them anything else.
If tomorrow JJK has a bad end, I wouldn’t really be moved because I hadn’t that much expectations.
MHA end being dog shit is more difficult to accept (I obviously don’t care that much at all) because I had far better expectations given the setting, the characters, the plot etc etc
MHA had more potential than JJK
