I can't say whether I truly like it or not, since I haven't watched an episode past number 3, and only parts of 6. What it comes down to, I think, is that we all want it to be Gunbuster, and its not. It also seems like they have gone back to the same well too many times here.
And, in the end, no money shot. They left us in the same place they did the first time around.
Part sequel, part re-imaging, part homage piece, I just don't think this one has the character or charm of the original. That's not to say its bad, I just think they missed the boat.
