I love the fact that you two were the first to respond. This just kind of ties into what I'm thinking that without the boomer nostalgia it really wouldn't have done anything (of course I do not mean this in a offensive way, being a boomer myself by internet standards).
I just don't think the franchise appeals to more modern audiences like say Star wars. But again, that's not really a fair comparison because Star wars has had more recent films I think and obviously cartoons etc.
Anyway, regardless I shall pick it up again sometime. I got to the Vatican from memory and I remember thinking Oh, that's a very nice looking croissant
