The Dr. Hoffman role was the one where I noticed the most difference between the 90s version and Helena's portrayal. I absolutely loved Helena in this role!
And I never would have recognized her if I didn't already know it was her.
I thought the Carolyn I saw in clips of the original show acted more adult and the Carolyn in Tim's version was a bratty teen -- mouthy, sullen.....
And Tim's Angelique was more feminist -- bold and overtly greedy and out to exert power for power's -- than the Angelique I saw before. The old Angelique was more interested in her personal life than also having a professional one.
I agree the characters mirrored the era the show was made.
