I really like the trailer.
I does look to me they are going to do quite a bit of pre-Third Earth stuff which is fine with me- it new ground yet it is not. Glad Grune is going to play a part for awhile. I wonder if the lesser mutants are Grune's slaves?
I wonder if they are going to factor Mumm-ra into the destruction of Thundara some how? I'm guessing based on the toy designs- Mumm-ra is starting out in this version with the Sword of Plundar- which according to the original series is what torn Thundara apart.
So much interesting stuff to come!
