One above-the-average episode. It is interesting to see Superman interact with the most dangerous villains of the Batman universe. Why we didn't see the opposite (like Batman fighting Darkseid or Toyman) in the series? Anyway, is a very good action-filled episode, except for the fact that Superman seems to be such a weakling (OK, is magic, but still).
Tala steals a magic artifact and Superman tries to stop her, but ultimately fails. Later on, Tala disguises herself as Lois Lane and fools Superman into rescue her, who gets trapped.
Then, Batman follows Ra Ghul trails to a hidden location in the dessert, where he helps free Superman and defeats a newly reborn Ra Ghul (thanks to Superman's powers), by making him fall into a stream.
Nicely done, but the action could have been better.
