I think now is a perfect time to revisit this series in light of He-Man Revelations given that both were misguided projects. What was the Thundercats? For those unfamiliar, the writers/artists had odd contempt for the main character, Lion-O. The series started strong with a tv movie showing Mumm-Ra's return and Lion-O gaining the sword, but soon fell into a pattern wherein everyone started shitting on the protagonist. Lessons learned were forgotten next episode, and most people on the project appeared to be more invested in Tygra for whatever reason. There's even documented evidence of one of the show's artists lashing out in Deviantart comments.
