Yes! I've been thinking the exact same thing. Watching TOS and TNG it clearly comes across that they're military hierarchies inspired in part by the kind of sciency and professional approach of the military / real life space program. The new shows reveal that the creators lack this understanding.

i felt the acting is too rigid, they need new actors, that can act better, using leftovers from STD wasnt helping them.

I can see that. I feel the same way sometimes but I just have to say, like it or not Discovery just ISN'T Star Trek.
