not as good as all the hype

a film so unique, intoxicating and bizarre that it not only demands another viewing, but is also forgivable as a satirical comedy where the jokes eventually take the back seat.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.

I saw this documentary about 12 years back in the Singapore Science Centre, my 1st time to an IMAX theatre. Was really impressedSome of the scenes make you feel part of the action to such an extent that I swear in one of them you feel yourself falling down. A few action sports selected for giving you that sense of how sports-persons drive their body to the limit in search of excellence are cycling, running, mountain climbing skiing etc.The physiological effects happening within your body are well illustrated. Don't want to say too much. Just go and watch it if you can in an Imax theatre. Good luck.

This movie is an IMAX documentary about how the human body can be pushed to the limit. This movie takes full-advantage of the IMAX experience by incredible shots on location such as a rock outcrop being scaled by a climber and a skier racing down a ski slope. Equally impressive are the footage sequences INSIDE the human body. You will "fly-through" the lungs, the heart, and its mainy blood vessels. In the future this film might become dated with new bio-medical films or specials. But they will not match the cinematography experience that this film format displays on the subject matter. So sit back and enjoy the "ride"
