So far it is, double expresso of grit - courage and resolve = take risk and sometimes it comes with mishaps, to put lightly. Ash's flashbacks from PSTD - yet tries to function as an officer who was a mutineer. XO Burhnam has to fake herself into comand in a Tyrant Empire. OH, XO Burhnam heh mutinied before. Saving Sarek's arse. Stamets' fusion with I term it Myconics and making super freaking crazy teleports. Lorca, though needs re-assessment and therapy, making, well, iron-fisted decisions, one that lands him the taser chamber.
Celestial: Too gritty is too soon to be conclusive. The pace is fast, dark and comes with twists, I rather enjoy it since my days of watching TNG, and DS9 as a youngin. I found them too agonizing and tedious. STD is adventure with a campaign setting in interstellar space.
