The only thing I wish TNG did from the get go, or kept from season 2 onwards, was Dr. Pulaski. She was simply a much better character and doctor than Crusher, she fit in with the rest of the crew much better as well.
Including, most importantly probably, naturally having the believable ability to stand up against the captain. There’s natural chemistry in that sort of dynamic, you’re almost waiting for a plot line to come along that splits them against each other.
I was fine with the character but hated the actress. She was an old crone and didn’t mesh into the ensemble IMO. The same for Natasha. Her acting chops were simple subpar.
I may be biased. I started in s4 and then went back to watch everything. I had no idea who Yar was and then didn’t like her acting. Her reactions to things seems forced. Her character had a rough upbringing but how the actress tries to portray it felt disjointed to me. The same for when she was trying to be attractive in scenes. I felt like she didn’t know how to act. And then when she was made to play a Romulan omg. She was terrible.
