"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.
When I heard that Jackie Chan and John Cusack were co-starring in a movie together, my immediate response was "Huh?". When I subsequently discovered that their odd collaboration would be in a Roman Legion epic, my immediate response was "HUH!?!".
"Yes, Madam"- the starring debut of both Michelle Yeoh and Cynthia Rothrock- is an acquired taste, as its flaws and eccentricities might be a little overbearing for you. But if you can get past that bitterness, enjoy the sweetness of the action choreography.
