The theme is simple: what was something that you used to be of a particular strong mindest of, only to find yourself doing a complete 180 and today having a totally different opinion and why? Could be anything, powersets, relationships, origins, parentage details, any aspect of a comic you ever felt strongly about but changed your mind on.
For example, I grew up Superman in throughout the 90s. Got on board when my mother bought me the Death of Superman trade and I never looked back. So I was big on the post-Crisis Superman being my one and only. One of those things I was set on is that Superman should be engaged/married to Lois. Always. Today, I'm of the complete opposite mindset. They should never be engaged. And should absolutelv never marry again. What changed my mind? I really think it was Superman: Secret Origin. While the miniseries ended up being a disastrous disappointment, one thing caught my eye early. How much fun I had when Clark Kent met Lois Lane for the first time and seeing them interact simply as colleagues and rivals. That was really fun for me, and made me realize something I hadn't really noticed until then..Lois and Clark in the present day and married had become really REALLY boring. It would turn out to be not too long after that the reboot would be announced, and the early rumors that the marriage would be leaving. Under other circumstances I might have been really mad but instead found myself really hyped instead. From then on I've been staunchly of the opinion that, while I feel the marriage was a good idea at the time to change up their relationship, it grew old really fast, and that the classic at arm's length attraction thing has far more legs.
