Ah! You spoiled it, RC! Now we know it's a straight up remake instead of the "Next Generation" stuff. Or did we know that long ago and I've not been paying attention?
So Diana -- lesbian catty good looks -- is replaced by Anna, sho sounds like she'll be a cross between Servalan and Cylon Number Six. Don't know if I like that... Diana's inherent evil and tomboyish qualities made her a great enemy, with John in the sort of "soft spoken deity" role.
Tyler Evans is the new Daniel. Nice to make that character younger, because Daniel was actually an uncomfortable bad guy. Forcing people to lick his boots, slaughtering his elderly neighbor, borderline rapist freak... On one hand, it made his exit satisfying in Final Battle. But, really, up till them it was just like...ick.
Chad is now in the role of Donovan's girlfriend, eh? Might be interesting, since she was woefully underused in the original. I would have liked to see her role expanded on -- the ultimate sympathizer, realizing the truth far too late.
And Father Jack is Father Andrew with teeth, it sounds like. Having Father Andrew ultimately become a naive sympathizer hurt the Final Battle, I think. All part of the retarded Starchild subplot...
And Erica Evans is both Juliet and Mike Donovan in one. Greatly simplifies the series, really. No worry about love, puts a strong woman in the lead without watering her down by a strong male role... I approve!
