Oh huh! I love the anime to pieces, and I actually thought the changes the anime made to the manga timeline made a lot of sense (putting some of Ed and Al's earlier adventures in the manga as flashbacks). If you think about the worldbuilding too hard, it falls apart a bit, but when you're watching, it's incredibly tense and horrifying. The thing that I liked the most with the anime was how much things affected the characters; you get the sense that no one and nothing is safe in a way that I don't quite from the manga. That said, I like what the manga's doing with certain revelations as well, and I find the worlds of both very cool.
