I share your dismay w/r/t the ‘origin story’ trope, and started typing a much more cynical comment. But it’s not like you can’t tell a good story within those parameters. Plenty of good prequels exist. And lots of people were not big fans of Picard’s efforts to advance the timeline.
The determining factor for me will be the quality of the writing. I haven’t seen this Black Mirror episode, but I’ll check it out.
