It gets really good after the first 31 episodes

Guilty

on my first watch of tng i straight up just jumped to s3 or 4, you pick up what you need pretty quick and skip to the good part

And Enterprise. It improved so much in s3, but good luck getting through 50 episodes to get there.

DS9 at least gets good towards the end of season one, and hits it's stride in season 3. It never stops being good from there.

TNG I swear is mediocre until like season 5.
