Fullmetal Alchemist: Brotherhood is a well-built shonen
I have watched the Original version as well
and this one is very Superior
There are plot points in the Original that don't make any sense and it's very grounded compared to Brotherhood but that doesn't make it better
Although that is also worth the watch
while FMAB is a true Shonen and things are at a much larger scale at the end
What I love about this series is the exploration of Alchemy and things like Automail
Really good worldbuilding
Amazing and very shocking plot twists
Also, there are various horror elements in this series especially ones that are Lovecraftian
And the characters are also very memorable especially Alphonse and his brotherly moments with Edward
and I got emotional at one moment when the ending song started playing during a very shocking sequence
This is a series that I want to watch once more in the future or even read the manga
