I like Advent Children, but not for the reason you put there. I first saw it right after I finished FFVII for the first time and I was pretty much in awe. "It's like Final Fantasy VII, but in high definition! This is totally wicked!"

And then I tried out Crisis Core for the first time and I'm like "It's like Advent Children... but I CAN PLAY IT! THIS IS AWESOME! " Though actually finishing was delayed because Gen kept making my video card crash whenever he used a limit break I generally loved it, though it's definitely not on the level of the original.

As for the rest of it I've just plain never seen it myself. Not all that interested in it either. Heck even from what I saw there's still some elements that I dislike (Genesis particularly) and some explanations that I tend to replace with my own assumtions either because the official explanations are lame or mine sound more fun (Gen's a glitch and there's some kind of crazy shenanigans from Touhou going on here cause Sephy knows Orreries Sun for some reason and there's a picture of Reimu and Marisa in the inn), but in general what I HAVE seen I can accept... at least for most of it. But Gen's still a prick.
