80 ok, let me start saying my opinion about the end of FMA: Brotherhood.
I liked it a lot. Tye fact that Al used Alkahestry to transmute Ed's arm by sacrificing himself was an amzing act that showed how much he loved his brother. After that th fight between the alchemists and father was also great and... then... the final... Ed sacrificed his Gate to save his brother. THAT WAS A TRUE SACRIFICE! I really enjoyed it and I would've love it even more if it was longer.
