I hate to be the sentimental one all the time, but I was thinking about this the last time I saw the show, just after I watched the documentary on the DVD.
That said, I think other than being a financial decision in terms of the obvious, choosing to close that show is not going to be an easy thing to do, and I have to wonder if the powers that be will continue to push it when it truly is past its due date because of how much is packed into it. On the documentary, there's a lot about how Rent is pretty much all that's left of Jonathan, and there's all of this heartbreaking stuff about his father seeing like, every production ever, because that's not just Jonathan's show, but it's all they've got left. I watched that and was just like "they can't close this show."
Of course the time'll come, but I think it will be when it absolutely *must* come, and financially speaking, that may not be all that soon. I'm not sure how I feel personally about letting it go out on a good note while it's still in okay shape, or about pushing it as far as it can go. But... well, there's my pocket change.
