Personally I did not like this cartoon very much. I do have to admit, that I stopped watching it after the first season. First of all, I love the Flash and even though I enjoyed most of his stories, the others did not make me curious. No offence or anything, but my favorite Lantern is of course Hal Jordan, so sorry John Stewart, but I couldn't care less. Same goes for Hawkgirl... where's Hawkman? I like the outfit and all, but it is He who makes it bad-ass. You? ... Not so much. And I know that this is about the whole League, but seriously, we need a lot more Batman and definitely more Superman! It is not enough to put them on the covers of the DVD! That said, if you are a fan of these characters from the comics you are set to love it! The drawings are actually great and the stories are very fascinating but this requires a proper audience. I'm unfortunately not part of that.
Kyle MacLachlan, David Boreanez, Kyra Sedgwick, Neal Patrick Harris and Brooke Shields, get ready for one of the best origin stories ever released!
If DC wants a good Justice League live-action movie, then they should take this movie into consideration. You already know the main characters, you know their friendship. What raises questions is how some characters like Flash or Aquaman came to be part of their great group and here you receive an answer to all of your questions. It is a wonderful movie and really great if you care for these heroes.
Lex Luthor is a hero in his alternate universe and he has come to our planet to ask for help from our heroes. Their evil counterparts have fought and destroyed all of the heroes and there is need for fresh blood to get a chance to destroy these bad guys.
