Spider-Man: Into the Spider-Verse

Alternate timelines, alternate dimensions, alternate spidermen who all come together in this film about finding yourself and becoming your best version you can be.  It's complicated, especially for a 10 year old. I had to pause this one on a few occasions to get my son up to speed.  It's a good movie with a very unique visual style, a great soundtrack and terrific voice acting.  Nicolas Cage is great in his brief "cameo".  Recommend, but I think 10 is the cutoff age if you want your child to understand the movie.
