MB, the irony of those Frid fans who believe no one but Frid can play Barnabas is that Frid himself is very open to what other actors bring to the vacillating vampire.
Also, for those who were surprised by Jackie Earle Haley's lack of hair in the pictures they've seen of him, here's a capture from last week's season finale (possibly even series finale) ep of Human Target
I'm sure he is. Frid is a talented and very learned actor. He understands that with acting it's all about expressing the truth of the character. It's only natural that different actors may have different ways of depicting that truth - but it doesn't necessarily make their choices right or wrong. If at their core those choices express the essence of the character, then they're all perfectly valid.
we shouldn't assume that any of the characters will be the same as they were in the original DS - especially as we've been warned by the producers that they felt that changes were necessary to update the story...
