People are into awful comic books. Such is the law of superhero geek culture.
I think it's mostly people never discovering the super-liberating experience of accepting and admitting that something that you love is bad. Honestly, it's incredible therapeutic. I'll even lead us off in a round:
Deadly Premonition is a janky mess that's just straight-up cribbing from Twin Peaks the entire time, which is
itself an over-acted corny mess. It's a completely terrible game and I absolutely love it.
JoJo's Bizarre Adventure: Stardust Crusaders is such paint-by-numbers shonen tripe that it basically wrote the book on what paint-by-numbers shonen tripe is. The only thing even particularly special about it is how amazingly homoerotic the whole thing is. I love it and I will watch it five times.
The Attitude Era was when professional wrestling completely jumped the shark, becoming too lazy to even bother with interesting gimmicks and a fun storyline in favor of instead running an entire decade of shows
about not having interesting gimmicks or fun storylines. It's my favorite decade of wrassling.
Now, I can't help with the BvS admission because I thought it was cat shit on screen and didn't derive a single moment of joy from the entire film, but I'm sure
someone can tell you why they love it anyway without trying to convince you it's actually good.
