I like the series. I enjoyed the old (with the exception of most of the red sky episodes) and newer (2003) incarnations.
The new show doesn't seem all that bad either. Though, I think they are trying to ride of nostalgia a bit by using the original theme a little too closely. Also, I'm not so keen on the pseudo anime stuff. It's like a mash up between the 80s, 2003, and Teen Titans.
