I liked Advent Children much more after seeing the "Complete" version. I also really liked Crisis Core, and felt them feels at the end. My hope for an FFVII remake is to try and tie the compilation up better, but also not to lose its magic (e.g. put more history about Zach, Shinra and the war, but don't shoehorn Genesis into the actual game).

Before Crisis, from what I've read, had potential to be really awesome and provide some further insight into Shinra and the founding of AVALANCHE. But from what I had read it seemed way over the top, falling quite short of my expectations.
