If the cast came across as overdoing the new parts or overacting, blame the director. It seems like they got no feedback at all per this interview: https://heavy.com/entertainment/star-trek/christina-chong-dishes-cute-hairy-partner
We were all playing different characters. Amanda (Row), the director of that episode… I didn’t get any feedback. I didn’t know if I was nailing it. I was asking everyone else, like, ‘You got any feedback, guys? Is she giving you any notes?’ And they were like, ‘No, we don’t know if we’re doing a good job or not.’ Then, I have Runa in my arms and Amanda comes toward me. I was like, ‘Oh, here it is. This is the part where she gives me the feedback and she says I’m doing a good job.’ She comes up to me and she’s like, ‘Oh Christina, I just wanted to say Runa is doing an amazing job. She’s nailing it.’’ And then (Row) walks away. I was like, ‘Okay… and me?’

If for some reason you wanted to play these again I believe they have been ported to Steam PC platform relatively recently.I had that problem years ago when trying to play Sherlock Holmes on the Sega cd. It was a point and click game where you had to watch scenes performed by actors in order to solve the mystery. I would rerun some scenes multiple times because some of those actors accents made it difficult to understand.
