I wish I could be confident in Genndy, but only seeing his animation work, I have nothing to base my confidence in, the reason being that this sequel deals with elements outside of his animation expertise.
I'm not at all saying that he's a hack or incapable, I just haven't seen anything with the exception of that 3 minute comicon clip that ended up on youtube. If there were a trailer or a clip of the work that they've been doing to show us then that would be one thing, but again, I know I'm beating a dead horse, but they've showed us NOTHING. No production stills, no behind the scenes diaries, zilch, nada, zero.
Of course, Genndy, Lisa Henson & Co don't have to prove anything to me/us/the fans. They can continue as they have been for months, doing the their thing without saying a word. They can continue this trend of estrangement but at this stage, it would be unwise and their silence only breeds our contempt.
This is the point where we as fans NEED to be involved, to get behind this project and trumpet it, even if it is indeed a direct-to-video endeavor.
I hope some one who matters reads this and takes action. The Power of the Dark Crystal needs us [the fans] to succeed. Period.
