I really enjoy the 2003 anime. I prefer Brotherhood, but I still adore the original anime. They went a little more in depth with the side stories (that they had up to that point...) Also totally fell in love with Vic in the 2003 series. I love me some dark brooding Ed.
FMA was really good but the ending made me think that they were going to add more you know. I have been watching FMAB on toonami and it isn't that bad I think it is better to watch FMA before FMAB because there are some parts where it brings back something that happened in FMA. That's just my opinion. neutral
