We barely watch movies anymore, because babysitting is expensive and the children don't leave many two-hour windows of being awake for streaming video. But when we do watch movies, they're usually Korean movies, because Koreans make better action movies than Americans do. (Or Hong Kong movies.) Every big Hollywood action movie is such an exact replica of every other big Hollywood action movie that it's as if you're already watching them on the airplane seat-back screen and forgetting them in real time.
So we went and saw Snowpiercer and there you go. American actors who want to be in action blockbusters should just all go work for Asian directors, the way European basketball stars go to the NBA. But Song Kang-ho should get the lead roles, because he's more charismatic than Chris Evans.
