Season 1 actually followed the shows title, we got a lot of "Strange New Worlds" and exploring in that season. This season was half filler and experimental bullshit, the kind of episodes that would feel like a waste in a 26 episode season back in the day but now taking up a 10 episode run. In my opinion only five episodes this season (Episode 1 "The Broken Circle", Episode 6 "Lost in Translation", Episode 7 "Those Old Scientists", Episode 8 "Under the Cloak of War" and Episode 10 "Hegemony") were genuinely good episodes that felt like they'd have fit with Season 1's best episodes. The rest was just a waste of time at best.
The show is way too young, and has too few episodes per season, to waste on experimental episodes and general filler. SNW was advertised as going back to doing what pre-DSC Star Trek did best, literally exploring "Strange New Worlds" and having more episodic stuff (but with actual character development and occasional serialized elements, unlike several of the old shows). This season just felt half assed, and like others have pointed out its also felt like they had a much lower budget, a lot of "bottle" style episodes this season just taking place on the ship or in easily modified sets with blatant green screen, at least thats what it felt like.
