the last few seasons of Discovery have been a bit bogged down by the stuff that has always made it a tough sell as a Trek series: overly ambitious, serialized storylines that aren’t compelling; new characters and environments that don’t impress; plot twists which can be maddening in their lack of logic; big storytelling swings which can be confusing and predictable at once.
