Phantom Menace is a good swashbuckler, like the rest of the Star Wars films. I liked it.
So how little kids are we talking about? I guess Star Wars would be ok for those about five or six and older. Younger ones might like the frog characters.
Just a comment on the frog guys. Some people didn't care for the chactors at all. Saying things like, "There just for kids, etc." Well they were supposed to be low tech I guess, but they went up against the robot armys, with basicly sticks and rocks. Knowing it's just a holding action. That take curage, and lots of it. Reminds me of the legond of the Polish Cav. units attacking Nazi tanks. Legend has it that some broke their lances against the armor of the tank. Guts, you bet, But so dumb, to waste that currage in a hopless attack. Breaks your heart.
