I have never seen the original Thundercats, but this is one of my favorite shows of all time. It is so underrated. It feels like it's inspired by Avatar: The Last Airbender and The Lord of the Rings. The animation and direction are amazing, the music is epic and really adds to the feel of the show. The drama and action are great, the voice acting is superb, and the show is genuinely funny. The characters have a great dynamic with each other, and the show teaches good lessons that don't feel preachy but add to the depth of the show.
