TNG had major problems in its first seasons, including a handful of extremely painful episodes which would never have been made (Troi In Love, Wesley Almost Gets Executed, African Tribal Planet, Tasha Dies [For The First Time], Data Has An Evil Twin) just to name a few, which would not have been needed if seasons were less than 22 episodes.
There were some standouts, Conspiracy and the Big Goodbye, and a bunch of mediocres.
For DSC, I found two episodes to be -annoying-, and maybe two more that just made no sense (chief of security getting herself Darwined). Once you've established the existence of the Spore Drive and its weird technobabble, its not so bad, the technological restraints are fairly consistent.
What I *don't* like is early in the season when Burnham takes the blame for the war, nor do I like that the klingons speak klingon - it should be mostly accented english, with klingon only used to establish that the show is really translating and they don't actually speak english. Waay too much Klingon subplot.
I find the characters to be generally more believable than on TNG (or Voyager).
