Or, which was my point, there are numerous reasons (including how it was presented) why it could happen outside of lack of clarity...OK. In that case I think it's fairly clear why two GMs might present the same situation with the same degree of clarity and at one table get buy-in while at the other table it falls flat.
Or in other words, the answer to the question you posed here seems fairly straightforward:
Those players who don't find it interesting are probably the ones for whom it is not interesting.
EDIT: It's not interesting because I don't find it interesting doesn't really speak to why one doesn't find it interesting.
