I prefer how more serious Brotherhood made Hohenheim and Al's reunion is,
but I wouldn't mind that comedic passed reaction and his memory of his armor.
But then the frequent comic relief is the biggest flaw of FMA.
I wish Brotherhood had the jealous moment of Winry, since in the anime she doesn't seem jealous at all, since she's smiling and doesn't make a grimace when she first sees Rose and Rose mentions Ed.
