I saw it and found it to be really moving. It makes a compelling case that the HMO’s havent got our best interests at heart. I think you should definately watch it, no matter what side of the fence you sit on. I have lived under social and private medicine systems (US and UK) and I know which one I prefer. The funny thing is I pay at least as much tax in the US as I did in the UK. The difference is that in the US at least 50% of that money is used for fighting wars, instead of keeping us all healthy.
There is going to be a lot of negative noise from industry shills and the ‘got mine, screw you’ crowd, but do yourself a favor and see it for yourself and make up your own mind.
