"The Shallows" seems to be an attempt to forge a marriage between critic friendly drama ("Open Water"?) and plebeian friendly entertainment ("Shark Night"?), although the relationship ends up being somewhat turbulent, if passionate.
I had liked "Lady Snowblood" during my initial viewing, but I think I only enjoyed it on a superficial level, believing it to be exploitation packaged as art. I was paying so much attention to the violence, sex and style that I overlooked the depth to be found within the story, characters and visuals.
"Operation Condor" was made during the perfect time period, as Jackie Chan had enough experience as a director, his star power allowed for massive budgets and he was still young enough to defy God and gravity with his jaw dropping stunts. It was the perfect storm for greatness.
"Riot" is bad, but not THAT bad and might even provide some surface level entertainment for a handful of viewers. Even though I was mentally acknowledging its army of failures, I never became bored, annoyed or angry. I was just very, very indifferent.
