Liking stuff ironically is bull. That's not the key. It's not about liking bad stuff because it's bad. It's about acknowledging something you like is bad, but enjoying it anyway.
I don't get the ironically part. I mean...I like many things that are bad, because they are bad, as it brings joy to me. It amuses me. But it has to be the right kind of bad and half the time the filmmakers etc. are very much aiming for that kind of bad anyway (see all kinds of trashy shark movies). It's like enjoying a bad pun. It can suck, you can admit it sucks, but damn it if it isn't fun.
