There was a time in the 1980s when Meryl Streep was very respected but seeing her movies felt like homework, what with all the dour subject matters and accents. The same can be said of Watermark, a well-made but dull documentary about water from Jennifer Baichwal and Edward Burtynsky, whose lauded Manufactured Landscapes was a similarly stoic, beautifully photographed, boring look at industrial manufacturing. The gist: The world used to have a lot more water and now we have less and we will lose more (including by printing large-scale coffee table books by Burtynsky, cough). So you could gain some CanCon points or you could go see Gravity again. (TT)
