Boeing 737 Max: Automated Crashes [video]
Right around 37:30 it shows how difficult it is to use the manual trim wheel to affect the plane's attitude.One pilot has to move all focus to it, without touching the other controls.It is still baffling to me how everything, from one sensor to a control system that can overwhelm the pilots with stick forces with no sanity checks in software, got through Boeing and then the FAA.
