Great Documentary with an amazing cast and great storyline. I remember that I was very impressed when I saw it for the first time... I sat for a long time after I ended watching Challenger: The Final Fight - Season 1, reflecting on my life. No other tv show has ever filled me with so much strange energy and got me so immersed in it. An tv show highly valued for me. I recommend to everyone who likes such tv series. You can watch it for free on this streaming website.
