For me the first thing that comes to mind is Tales from Earthsea. I don’t think it’s excellent or anything and has plenty of problems but people act like it killed their dog. While it has its problems that have been covered extensively, I think it has a beautiful atmosphere and art.
IMO it would have been better received if it wasn’t advertised as an Earthsea adaptation and was just its own thing.
Secret Invasion had me close to hanging up my MCU fan hat. The Marvels is the first movie I didn’t catch in the theater, but then I watched it on streaming and it really reminded me why I love the franchise so much. It’s got its pacing issues and the first 30 minutes are clearly the swiss cheese left after some heavy revisions, but it’s just so fucking fun, and Iman Vellani is goddamn delightful.
X-Men '97 manages to hit all the good nostalgia notes from the old TV series while getting me excited for what comes next, and I’m going back and re-watching Agents of SHIELD now. I thought I remembered Season 1 being kinda humdrum before the Hydra twist, but it’s fun seeing all of Ward’s plot beats knowing what is coming.
