> When films aren't available on any of the streaming services I subscribe to, what do you expect me to do? Pay another £60 per annum to watch one film on a streaming service I'll never use again? I read somewhere there are 1000 streaming services in the UK, and over 2000 in the US.

Yes? Especially when you actually normally are able to use a thirty day trial, or pay £5 for a single month without a rolling contract, or just don't watch the title, or go and purchase/rent it from iTunes et al?

All of those are perfectly legitimate options.
