I'm with you, I did not really like 1-2 much (despite liking the characters, sets, costumes music, etc.) and 3 was an improvement, but season 4 I actually thought was phenomenal and what I want to see more of in Trek, specifically the slower pacing and big weird alien-aliens, and a conflict not solved with pew pews.

I feel similarly with Enterprise, Season 4 of ENT was so good, so I'm excited to see if DSC S5 can keep it up.
