Australia occasionally produces some truly great movies, Mad Max, Crocodile Dundee et al.......this is not one of them!
Wooden, almost comical acting is rife. Stages, costumes and special effects are right down there near the bottom. Yes, I like that some Aussie actors got to make some money in these hard times but crikey it is to watch. The plot is a well trodden one....back in time to save present day humanity. The planet is without trees and oxygen is a commodity (this may explain the acting).
IF you have watched absolutely everything else on Netflix then you have little choice I guess. Or you could just go lay on your bed for an hour or so and dream something up better
