I just re-watched Strange World over the weekend and I really like this movie! Here's what I think it has going for it:
1) It isn't a sequel or a retelling - it may be some features of Journey to the Center of the Earth and Dr. Seuss, but it's pretty original.
2) The characters have good depth to them - sure there are some repeated tropes about kids and parents, that ha[[ens. But overall the characters are well developed and fun.
3) The animation is awesome! - I think this is the best part for me, it's like if Avatar was an animated movie made for kids. The animals are gorgeous. I wish more time were spent with some of them instead of just Splat.
4) It's pretty funny - gotta love Legend the dog for comedic relief.
So yeah. I think that this movie is pretty good. I like it better than Soul and Inside Out. I didn't like it as much as Luca or Encanto. I don't expect it to have a ride or character meet and greet at WDW (although it would have fit right in at EPCOT with either Body Wars or Living with the Land). But, I think it got short-changed and definitely deserves another watch.
