Just watched EP.1 of the third season, and I am on board this ride!
Spoilers:IMO this is what this show should have been about from the very beginning! When before they were trying to fit events into an already existing story, now they can tell a completely new story without any strings attached!
Now we have great hooks for a potentially multi-season story arc. Find Discovery, figure out the mystery of what caused the burn, and begin the work to rebuild The Federation. I just hope they take their time in building up on the mysteries they introduced. I think they are going to find Discovery in the next episode though.
This feels almost like a post apocalyptic version of the ST universe, which it kinda is. I think our main characters are going to have a huge advantage compared to everybody else when they can warp around without using dilithium, with their spore drive. I like the idea of the remaining dilithium being the most valuable thing in the galaxy. The tech also feels strange but believable for a galaxy almost a 1000 years after TOS.
I can't wait to see where they go with this!
