Anyone a fan of the original series?
I watched a few episodes last night from the Leviathans storyline. They are on Hulu-- this particular story is from early 1970. With the exception of classy Joan Bennett who understands the point of subtlety to convey emotions, most of them scream their lines and are way too over the top. And these are performers who went on to success in other things, so I think the problem is with the director encouraging them to overplay it.
I love what the writing suggests, but the hammy acting and the silly werewolf costume and obviously low budget make it very amateurish to me. I can see why people find it entertaining, but not as a serious form of television.
And though they have Jonathan Frid's Barnabas supposedly pining after his late Josette (and her various incarnations), there's such a strong gay subtext with the character, it nearly overshadows everything else.
