I wouldn’t say mishandled but I would say both Disco and Picard’s first two seasons were incredibly sloppy due to a clear lack of planning, vision, and the difficulty of transitioning to a fully serialized format.
By contrast Lower Decks and Strange New Worlds were really able to find their footing quickly because they had season-wide arcs but outside of that they were generally episodic and allowed for a lot more exploration of the core of the universe. This is just a better format for the franchise in my opinion.
I find Kurtzman is occupied with making the series more cinematic than it needs to be. Overly cinematic Star Trek results in eye bleeding lightshows like the finale of Disco S2, while grounding the shows a bit more allows for more character growth and development. You can’t just always have Sacrifice of Angels all the time, you need to cut it with some Take Me Out to The Holosuite.
