The SNW/LD crossover episode was one of the most anticipated things of 2023 for me and fully delivered, just the perfect loveletter to being a Trekkie whilst also building on a fair number of personal plot developments.
If you’ve not already watched it I’d check out Prodigy too - it’s probably the most underrated Nu Trek series imo being aimed at younger viewers. That said I loved it as an adult (ostensibly) and am praying season 2 gets picked up soon.
As to the topic, I can’t think of anything as even series heavy on world building/low on action at the start like Andor or The Expense drew me in from the beginning.
