Just watched it in the cinema yesterday. I can say that this movie is THE BEST movie in the last 10 years.
It brought me to tears. Yes, your "Iron Muaythaison" Mod cried 6 times during this movie. If it wasn't good, I wouldn't cry.
The fight in the end is just "perfect". Words can't explain it.
If you don't watch this movie, you wasted a life time.
