If you didn't like Lower Decks you probably really never liked Star Trek. Strange New Worlds and Starfleet Academy also happen to be better than... a significant portion of the classics (DS9 will never be surpassed and that's okay).
Lower Decks in traditional Trek fashion had a rough season 1 but was stronger later. SNW an Academy had probably the best two season 1 performances of any Star Trek shows ever produced. There's one gripe about Academy that you can grant: The theme song sucks. Other than that, perfect.
There's some legitimately challenging writing decisions in Discovery and Picard, but if the three shows you mentioned ruin Trek for you, you never got it in the first place.
I couldn't get into Lower Decks. And I love Star Trek, so maybe you don't understand the full range of Star Trek fans. I personally love NG but couldn't get into DS9 or Voyager. I disliked Discovery but I love SNW. There are all kinds of Star Trek fans.
I love Lower Decks but it’s not like TOS at all. It’s more like a love letter to TOS. Strange New Worlds is VERY much like TOS.
