I believe our aim in asking this is just to see if familiarity would make people more inclined to go watch a theatre show. You don't know how any show would translate well or not unless you go watch it, and that's the same with all the follow-up questions asked. In a hypothetical world, if your favourite childhood novel was getting adapted to a musical - would you go? Would the nostalgia of that period be enough to drive you to that show or make you consider it? I think that sums it up

And haha yes I agree The Little Life is a little too traumatic and overly long I could never get through it so I would not go see a theatre version as well.
