I really feel like mostly everything did hit in Secret Wars, even if some "Best Parts Only" storytelling was in effect. That said, the Captain Marvel/Mr. Sinster stuff felt like it came way out of right field, like there was some mini that was supposed to explain it that was dropped or something. I think it was a sort of interesting combination of characters and subgroupings though. Is there any chance we might see that version of Carol again to get her fleshed out, maybe as a villain?
