I really enjoyed that - I thought it was extremely entertaining and great fun.
There are plenty of questions but that’s all part of the fun (Im intrigued to know what Burnham’s history with the Vulcans is in the mirror universe).
I don’t think it’s fair to say the characters are all assholes and that they don’t trust each other. Burnham is pretty sound and obviously trusts security bloke (probably wrongly so), Lorca certainly trusts Burnham etc.
I think the whole thing’s ace.
