I'm probably a minority on this one, but I wasn't even that into Nicholas Blair...nothing wrong with Humbert Astredo, I suppose there were just too many supernatural beings running around during the Adam storyline. Maybe I would have enjoyed him more if there had been no Adam and Eve subplot and it had just been Cassandra & Nicholas vs. Barnabas & the Collins family. He had too many scenes with Adam & Eve, and they both drove me up the wall.
Actually, my viewing history of Adam/dreamcurse/angelique/nicholas Blair is petty sketchy 'cause I stopped buying tapes once I realized how silly it all was. I also FF through all Eve/Professor Lang/and anything to do with the "experiment" including segments when Barnabas was saying "experiment" every two sentences. I focused primarily on Nicholas Blair/Maggie Evans stuff (hot some of them) I loooove it when Nicholas is seducing Maggie at the Blue Whale. I saw some of the early Adam/Willie cruelties that are fairly strong due to excellent Karlen and Robert Rodan. I also enjoyed much of the Angelique/Nicholas bantering, but, you kinda knew Angelique would eventually kick his butt. She was the meanest of them all.
