I know I'm a bit late to the party here (since the last episode aired in July) but I just finished watching the entire series and I have to say I was pretty pleased.
Granted, I haven't read the manga, so I can't speak as to how closely they followed the plot, but the series as a whole made a lot more sense this time around. Things were better explained overall, even though there seemed to be more twists.
I really enjoyed getting more of a background on Wrath and how he came about becoming Fuhrer, as well as the level of corruption in the government and how Father had been manipulating them all for hundreds of years. It was also nice to see all of the homunculi actually show traits for the sins they were named for. I was confused when watching the original series as to why Sloth was named such when she showed absolutely no slothlike behavior, not to mention that Pride didn't seem to be all that prideful. Also, Sloth in Brotherhood is hysterical. Everything is a "bother" even living and dying. Envy's actual form was pretty amusing as well.
I also liked that they spent a lot more time telling us about Hohenheim's background and how he and Father came to exist. I didn't really care for the whole Dante **** in the original anime. The whole Xerses idea was a lot more interesting I thought, as well as Hohenheim living for so long because of the Philosopher's Stone being inside him, instead of body jumping.
The ending in particular was a lot more pleasing too. Al still got his body back, but without the consequence of Ed ending up in pre WWII Germany, which never made any sense. I also enjoyed the bit of angst with Ed and Winry's relationship. Their way of telling each other that they loved each other was really funny. "Equivalent exchange! If I give you half of your life will you give me half of mine!?" "You idiot! I'll give you all of mine! Wait, no not quite all... 90, no, 80, no 85%!" So cute. ^^
Did anyone else finish watching this? What did you think?
