While I personally don't think you have to root for Barry to make the show work, if you don't like increasingly dark storylines, then yeah, I'd probably say stop. I mean it's painful for me to say because S2 simultaneously has some of the most creative and funniest episodes too, but no point in putting yourself through misery if you don't want to.
I've decided to put my fears behind me. I'm not going back.
