As someone who never watched the original and is probably never going to, I'll just say that Brotherhood itself is pretty good and serves as a stand alone series separate from the original.
They can be watched independently of each other, as far as I know.
Maybe the early episodes of Brotherhood aren't as disappointing if you don't realize just how badly they butchered the Nina story. I just don't think the early episodes will have nearly as much impact if you have no prior experience with the franchise. The Brotherhood staff assumed that everyone had already seen those episodes, so they just hacked out some lackluster condensed versions of them.
But everyone should watch the original, because it's a great show.
