I watched a few episodes of the original series, and I also wondered why he turned it into a comedy. It is a strange idea to flip it like that, but I think it might be good. (Haven't got around to seeing it just yet!)
I just remember it being a soap opera and it was all dramatic with a hint of romance, and Barnabas was a very intruiging[sp?] character. I also remember David could see him, and his dad being all "Who are you talking to?" lol.
I have yet to watch more of the show. My mom's a big fan of it, and my aunt is too.
