Quite frankly i like what they did when if came to recreating the TOS cylon's sorta speak for Razor. Razor in fact was really the only ep i ever fully watched of Nubsg. There were elements in there that worked well.
Now don't get me started on the New Cylon Centurians they made. Quite frankly i could never really see that design element. To each his own.
I do like what Mikala did here with his "The older model thread". I think that would have been a true progression of what we could have seen for a future cylon. Probably in between what we seen from the TOS and DeSanto's version.
