It might not quite compare with Kurosawa's greatest movies, but "The Hidden Fortress" is good entertainment with an interesting story and characters. Toshiro Mifune is enjoyable to watch as always, and although most of the story is played for action and/or humor, it does have a couple of powerful scenes as well. The story of a defeated general trying to lead his princess past the enemy to safety is given plenty of twists and turns that give all of the characters some good moments.
Along with all of the action, there are some pretty good characters, with Mifune, as the general, a big part of holding everything together in his interactions with all of the others. The rather spoiled princess learns quite a bit about life, and the two greedy farmers learn - and often quickly forget - some lessons of their own. There are also some good scenes with an enemy general. Most of it works well, and it's an entertaining movie.
