Bluth is a very talented man, and his work in those films is wonderful (don't like Small One, myself). I can't stand Robin Hood simply because it completely wastes their one shot at telling the Robin Hood legend by turning it into a collection of pleasant comedy skits. Pete's Dragon has major script, acting and directorial issues. Pooh is 2/3 fantastic (sorry, Tigger Too). Rescuers is a fine film.
My very favorite Bluth work, however, is the Dragon's Lair Trilogy. Just bought it
again, this time for my Nintendo Switch.
