I have that bookmarked already, but just can't muster the energy to watch it.
He might have some valid points - there's a lot of cynical corporate crap pushed in the name of green-washing, and a lot of suspiciously pain-free purported techno-fixes to climate-change.  I'm not that excited by electric cars or micro-solar/wind for example.  And Carbon-offsetting appears to be mostly a con.
On the other hand he might be going too far the other way with some workerist leftist dismissal of all environmentalism.  Can't tell, till I watch it, which I can't find the energy to do.
Plus, also, to be honest, Michael Moore does tend to use cheap tricks in his movies.  As always, the written word is more trustworthy than moving images.  People who work in that medium are always propagandists, really.
