A botanist (Bruce Dern) on a deep space mission tries to stop the corporate machine from destroying his small "forest" aboard his inter-planetary freighter. When his shipmates decide to implement the order he takes matters into his own hands. It is vaguely portentous of events yet to come - and has a poignancy about not knowing what you've lost until you haven't got it any more. It's the first film I recall seeing where there are droids - in this case, drones - Huey, Dewey (Louie has broken) that are given some semblance of personality and they do inject some much needed bursts of humour into this rather slow-moving sci fi story. It certainly has a message (climate change, warming etc.), but after a while it becomes quite laboured and slows down to a snail's pace before quite an abrupt ending. Interesting, but no classic...
