I didn't like it when I first saw it, and there are still parts that I don't care for, but overall, I'd give the series a B+.
Things I'd change about it to make it better for me:
I would have just killed al off at the beginning
I would also like it if Edward wasn't as young as he is cause then I wouldn't have to deal with...
Edward longing to be taller. That joke is done to death in the series.
Other than that, it's ok. I still don't watch it religiously, so I don't know everyones name.
There have been a few episodes that caught my eye tho, like the one where the guy with the x on his head takes a chunk out of Al and Destroys Eds arm. Or the one where he meets the Flame Alchemist for the first time. The Flame alchemist is prolly my favorite Character.
Good times.
