I definitely agree with you. While I didn’t like a lot of the elements of Disco season 1, it had a genuineness that was really compelling. Season 2 corrected the things I personally didn’t like but kept the heart and soul which has made it some of the finest modern Trek in my opinion. Season 3 was alright I suppose, but didn’t have that spark of authenticity. I’m dubious about anything more from Disco.
The big issue for me is also the show centering on Burnham. Season 2 put her along side Anson Mount’s Pike which balanced the scale nicely and their personalities played well together, but other than that Burnham has always felt like the main character of a CW show to me. I don’t know if it’s the writing for her character or the acting, but she’s a weak point of the show to me. Doug Jones on the other hand has been incredible and I could watch him play Saru all day 😄
