My reactions:

I think Al did grow because, what I got from it with my limited comprehension, was that the gate was just like a warptunnel to another dimension ~_~ Which I found incredibly lame. I also found it lame that DAnte could control it.

I can't figure out what happened to Dante and Gluttony cause they both disappeared. So I guess they killed each other.

The whole Envy thing annoys the hell out of me ~_~ It seemed like they were just trying to get rid of all the sins and were like "Hmmm..let's just make him disappear somehow."

For the Roy/Riza thing, I felt that they really killed some of her characterization just to set them up as a pair. I'm also rather annoyed that they didn't really do anything with Havoc who was also really close and important to Roy ~_~ In general, I think they really screwed up there. I used to love the military interaction and now I'm just going "Dammit ~_~"

Ed does still have his automail because we saw it while he was packing/trying to pack.

I'm upset with the ending. I was expecting something more and they really let me down.
