I didn't watch it, nor do I care to quite frankly. Maybe this is an unpopular opinion to have on here, but Mr. Olympia is fucking disgusting to watch. This is a matter of subjective opinion, of course, but my concept of the absolute pinnacle of the human male physique is more along the lines of Arnold, or Serge Nubret, or Frank Zane than Jay Cutler or Phil Heath. Again, just my opinion.
Edit: I should note that I've met Phil, and he's actually super nice. Really humble dude. I've heard he was portrayed as a douche in the film, but unless he's taken a total 180 degree turn in terms of personality over the last few years, he's not the douche that he's supposedly made to be in the movie.
