Full Metal Alchemist - the flaws?

*Warning spoilers*

I've been rewatching it recently. Minus its tracking off from the manga story, if you look at the series at itself it is quite brilliant. The tragedy is plays is quite brilliant. And when the comedy comes its just hillarious (the episode with Al versus Roy). Just that when you watch don't expect a lovey dovery ending or feel. The series central theme is tragedy. You will cry sometimes watching it (Nina).

The parrelel universe was a real bad part of the series. Ridiculuous concept. But other than that as an anime series, its quite perfect. Are there any other flaws in this series?

Flaws?

I thought that the first bit of the show was promising-- there was a real edginess involved with the poor little girl and such.  Unfortunately, I think that the end of the series didn't deliver on the promise, instead shifting to a much more formulaic storyline.  I stopped watching around episode 30 when I lost the last little bit of remaining interest.
