If Jhin had offered a different thematic perspective when you played him, I would like him better
See what they should have done is have it so when you play as Jhin, the game changes. All your abilities and attacks seem to evoke a sense of beauty with colorful particles like the flowers, smoke, trees, etc. Meanwhile the enemies see just plain old violence to really hit with the crazy serial killer thematic.
But they didn't really do that, and that's disappointing to me. I felt Riot could've taken advantage of something great and really evoked a stronger connection to the champion, but chose not to.
