I learned Olympic medal gymnasts are as good at acting as actors are at Olympic medal gymnastics.
I learned the guys named dropped other mid 80's Olympians a lot later than I thought they would.
I learned having your interesting backstory of having a mother that's Indonesian and nothing else is not actually interesting.
I learned using gymnastic martial arts on a stone pommel horse while fighting insane medieval peasants is not the most bizarre thing I've ever seen.
I learned the director was actually pretty good. He had no real actors and an absurd screenplay, yet the movie was shot and edited very well given the limitations. Then again, I'm sure he was sorry he couldn't direct Bruce Lee again and was reduced to martial arts gymnasts.
I learned, like the guys, to my shock and horror this is based on an actual book. WTF?
