I'm approaching this the same way I'm approaching Advent Children. With cautious apprehension. IMO, it will go one of two ways:
1.) Absolutely to die for. I mean, they hav, in both cases, a very strong storyline to work from.
2.) Absolute Crap. The law of sequels people, and this one has some mighty big shoes to fill.

I figure when/if it comes out, I'll give it a rent.
