I've see the first couple of seasons of it, and slowly watching more as my partner enjoys it. However, it is a bit too dark and confusing for me (especially trying to tell the various versions of the cylons appear....). I haven't seen much of the original (one or two episodes), but it seemed much less dark.

I'm not particularly into the new ST - I've seen both films and they are okay, but no where as good as the tv.
