“Tides” (**1/2 out of four) was a moderately compelling but muted melodrama set in the distant future in which Earth has become a giant wasteland and a shipwrecked female astronaut (Nora Arnezeder) struggles to fight for survival and must decide to save the planet or save herself as she tries to make sense of what has happened since she was gone. Yet another bleak futuristic story in which Earth has become desolate and debauched, dressed up with striking and moody cinematography from Markus Forderer and held together by Arnezeder’s strong lead performance, but story never builds much momentum and actually gets slower as it goes along. Originally titled “The Colony” until the filmmakers likely realized there was a 2013 film of the same name and with a similar story.
