It wasn't original, which is what someone else mentioned earlier in the thread. The only original part occurred when Ed kicked and flipped off of Greed, then stabbed him. Everything else was taken from the manga.
And it wasn't visually impressive, one person or no. That's just my opinion, though, you may like that scene as much as you wish. Perhaps it's more impacting to someone who's watched the anime and takes into account its dramatic importance?
I'm just seeing it on "how well done is this fight?" and its... well, I thought I'd be treated to a totally new fight. As it is, the fight is better rendered in its original format.
