I think I enjoy the comic book series better than the light hearted show. The comic book has a more dark, mature, serious style to it that can't really be seen in the animated show. The only time when the show is taken seriously is when Slade appears on the show, then the whole episode is about finding and defeating Slade, the same villain in the comic book. But since Slade is supposedly dead, the new episodes are being less serious to just plain weird. In the comic book, some of the characters look different and also some of the characters in the show aren't in the book and vice versa. In my opinion the creators of the animated series are trying too hard to make the show like an anime with chibi and kawaii moments and all. Maybe they wanted it that way to balance out the seriousness of the Justice League. Not sure about that theory though.
