Treasure Planet and Atlantis the Lost Empire are both some treasures from the end of Disney’s 2d animation era that were both kinda box office bombs. I also personally enjoy The League of Extraordinary Gentlemen even though that was another box office bomb.

Generally like the more disliked Star Trek movies too. TMP is gorgeous and a very Star Trek story. Search for Spock is also great and introduced us to some ships that would endure for a very long time in the franchise’s production. I need to revisit Final Frontier as I suspect that in my current more mellow state I’d be able to appreciate the good parts of that.
Also enjoy the much maligned later TNG movies, but this is getting a bit long.
