Treasure Planet (IMDB) (Netflix)
Robert Louis Stevenson's Treasure Island, animated, plus an assertively dubious interpretation of the laws of physics that my 4th-grade niece and nephew instantly deconstructed. Jim the troubled teen finds a map to Treasure Planet, commissions a voyage aboard a galleon/spacecraft, and does some growing up while searching for the loot and fighting off a ne'er-do-well crew.
There aren't many surprises, but some decent messages about loyalty, responsibility and selflessness. The voicing cast of Emma Thompson, Roscoe Lee Browne and Martin Short, among others, is sharp and the action well-paced. The kids responded well to the humor. Not the next Disney Classic by any stretch, but you could do worse.
