Yeah, I don't know if I would say I regretted it. But it wasn't very good. And I did read it because it was recommended. So I guess that counts.
I don't know that I've ever read a comic I regretted reading. There have been lots I didn't like. One that comes to mind is Watchmen (I know, I know). I started to read that on a recommendation and couldn't even finish it.
It's, The Boys, for me. It wasn't a bad comic. It just changed how I saw superheroes. I couldn't finish it because of the angles I never thought to venture into. Very good story but ****ed with my head in the hero-verse.
