I enjoyed The Batle of Four Armies and the "promise of the new premise", but as it is usual with Discovery, storytelling kinda suuuuuucks! And a lot of that has to do with the dealing with Red Angel storyline. First they´ll shock audience that it is Michael. Than it´s actually Mama Burnham. Than Michael is Red Angel 2.0 (at least it´s explained somehow), except as others said, we are not sure,how she stopped Ba´ul (except some general idea that incursion itself put havoc in their technology) and... So she was the one on the asteroid. Which makes the whole thing about Mama Burnham repeatedly saving Michael´s life even mor flimsy.
My memories of Mass Effect have come to life once again, as the fight Nhan and Georgiou vs. Leland kinda reminded me boss battle with RoboSaren.
As always, the emotional resonance and fanwank work well, but it could have been so much more.... Well, my father will definitely look forward to season 3 very much.
