Legacy was a perfect episode of Thundercats and I really enjoyed watching this episode because Lion-O is taken within the Book Of Omens and has to re-enact the past in the body of his ancestor in order to gain access to the Book Of Omens. It was awesome to see more background about The Book Of Omens and The Sword and Gauntlet and Mumm-Ra. The animation was awesome and Mumm-Ra's pyramid ship was sweet, it reminded me of a Goa'uld Mothership from Stargate SG-1. I almost wish they would do an animated series of Stargate SG-1 starting from the beginning in the same style as this show. Anyhow there was a lot of plot and character development in this episode and now Lion-o has a specific mission giving shape to his quest. I look forward to watching the next episode of Thundercats!!!!!!!!!
