I really liked the pilot, and enjoyed the show while it was on, but I have to say, it doesn't really hold up very well. The animation got more questionable as the series progressed (like they were cutting corners, and getting sloppy), the storylines were simplistic and overly moralistic. There are some real gems in there, the premise and characters were awesome, but it could have benefitted (IMO) from a more mature presentation. The same could be said for a lot of those kid shows, though, such as He-Man (which I preferred in the original comic with toy story format, instead of the "Prince Adam- Secret Identity" stuff).
From the reviews I've read of the DVD set, the quality is really poor on many of the episodes. Soundtracks missing, jumpy "camerawork". One reviewer mentioned that it looked like they used bad VCR tapes as their master copy.
Think I'll wait for a rerelease or something before I invest.
