I'd say the low ticket sales coupled with scalability problems was probably the thing that brought about the end - possibly a surmountable problem, but one that takes a lot more time and capital.

(ie, each showing requires staff at the very least to collect tickets - he makes reference to smoking and drinking with the bar staff).

That's the sort of problem that, if you come across it, and you're already low on energy + resources, is enough to finish it off.
