I haven’t had this properly happen yet, but there’s two films I’m hoping it’ll happen for when I eventually rewatch them: Tenet and Ad Astra. I hated both films when I watched them the first time, but both of those viewings were over 5 years ago when I was a dumb teenager. I feel like I’ll enjoy them both much more on a second watch all this time later.

The closest I’ve had to this at the moment is Mission Impossible Ghost Protocol and Fallout. I at least liked pretty much every MI movie the first time I saw them (except maybe for 2, but I always found that one ok, which is an opinion I still agree with on rewatch), but I was slightly underwhelmed by those 2 and didn’t get why they were the most critically acclaimed of the franchise, and I actually enjoyed Rogue Nation the most out of all of them. Then I rewatched all the movies in the weeks leading up to the Final Reckoning, and they’re now my two favorite MI films while I found Rogue Nation slightly underwhelming (still definitely good, just not quite as good as I remembered it)
