Thundercats is a great show. One of my favorite of all time and truly a classic. Best show I watched as a kid and first one that I truly loved.
The animation and sound is awesome considering the time it was made.
The characters are very carismatic, even the enemies. Sotimes I remember I cheered for the enemy to win just for once, but they always lost in the end. Only small victories in the battle, but the good always won the war.
And this anime is specially good for children, because despite the action it shows a moral sense.
I don´t give a note 10, only because it doesn't have an end it deserves.
