No, she not just the lead, she is the only character that matters. She IS the show.
I do not remember such lead character treatment in any other ST Series. That is why I compared her with Picard.
Picard has earned his own series after decades of playing the role in a show that it wasn't about him all the time, not even half of the times.
In Disco, from the first moment they are trying way too hard with her.
They just amplify her so much that she ends up like some kind of caricature.
The whole scene when she landed/crashed on that planet was so overdone.. Everything is way too much with her.
Even in the scene she was under influence, which I found cute, she overreacted.
They have to tone her down, let her character breath a little.
