Interesting movie that has the capacity to move the spectator at least temporarily to a neutral platform of observation including self-observation.
It actually can be utilized to explain why people so often refuse to understand PO. In one scene they talk about the inability of the indigenous people of the carribean back in the 1400's to "see" the ships of Columbus at the horizon since these "could not exist" as far as they were concerned.
Likewise is the message that our carbon-civilisation has an sudden end-point "not acceptable, since it can't be true". source
I rented the movie through Netflix and do recommend it.
