Somehow my post got gobbled up.
The premier was awesome.  I love the myth the show is developing.  I also did not have much hope for this show but I am pleasantly surprised.
I loved the look of the show and the animation was top notch.  The giant robot thingies were cool but for me the Clerics stole the show.  Jaga was a badass in the old show but not he is even more of a badass.  I'm not sure about Cheetara being a Cleric but given how well the show is written I think it will work out well.
I wish we had gotten more focus on Groon, his betrayal, and becoming The Destroyer.  His transformation was sudden and felt thrown in.  Mum-ra looked really creepy in his red robe priest form.  I was also surprised to see him outside of the pyramid in that weakened form, instead of the muscle-bound creature of evil that he turns into.
I liked the Robear Burbil arm and the other trinkets in the merchant shop.  They were a good foreshadowing of what is to come.  I wonder what Mum-Ra meant that the Eye of Thundera was his?  I also liked that the Sight beyond Sight is a product of Lion-O's destiny with the sword, rather than just an ability of the sword.
Anyway, there are too many cool things to discuss with just this one episode.  Can't wait for more.  I just hope it lasts a long time (and not suddenly get cancelled like Symbionic Titan) so we can enjoy all the revelations they have planned for us.
