I've said it before, but it bears repeating: the DVD release of Thundercats is pretty much a big "fuck you" to the fans. The quality is about VHS-level, the sound is mono, the episodes are in fucking production order so that Lion-O's Anointment is all split up, Exodus is the cut-down TV version instead of the extended version that was released on VHS, and the second episode was originally released with no fucking background music. It's a quick, cynical cash-in, and I hope that it gets the Transformers treatment and rereleased by somebody who actually gives a fuck (sup Shout Factory).
Also, I don't understand the reckoning where the show's only listed as having two seasons. I mean, okay, it had 130 episodes, and 65 of those were in a single season, but...the last 60 were spread out across 3 years and clearly bookended with 5-part story arcs.
tv.com corroborates that order, and claims the show ran its complete course by 1986, but
Wikipedia claims (and my memory absolutely 100% supports this) that the last season ran in '89 -- though it mysteriously loses original airdate information after '85.
