Never watched the show (well, saw a few episodes on tv but thats it)
Should I start with the original series or with Brotherhood?
please no bully
-More focus on characters
-More characters in general
-Lots of side stories/filler (if you like that)
-More focus on (and better) story
-Almost no side stories/filler (all main story)
Start with original but watch both. I do think Brotherhood is better, but original is also pretty good. Also, Brotherhood seems to kind of expects you to have already seen original, so it glosses over bits that were more in depth with the original.
Because Brotherhood is better, I think you'll be very disappointed with original if you watch it second.
Haven't read the manga but it probably is the best one.
