Lets see, I agree on the point that a more dialouge driven clip should have been chosen. That seemed kinda pointless in the end, however, the voices I did hear, I enjoyed.
I'm not going to entirely dismiss this, because I have heard Cloud, Tifa, and Sephiroth's voices already, thanks to Kingdom Hearts 2. I enjoyed their voices, and I honestly thought Sephiroth's fit him perfectly.
I am actually looking forward to a very good dub on this one.
