I like Kai, and after seeing how much of a dick Phil is I hope he wins. It was probably for the movie. I wonder if Phil was acting like a jerk off on purpose for the film or he is really that way. If he is I wish Ronnie would come out of retirement and crush him.
Yes, it's only a movie....which requires a good story.....which they still failed at.
Just like Pumpin Iron....Arnold purposefully went over the top, but it was fun and we can quote him 30 years later. They also added drama and rivalry with things like the stolen shirt.
Same things happens now but maybe even to a greater extent.
Phil lines his driveway with lambos? What, so they can breath or get a suntan? And takes bubble baths for the media? No, they were doing everything they could to make a champ as cocky as the old one (Arnold).
Then, they needed a Lou. That's where Kai comes in.
Kai's not poor. He drives new vehicles, doesn't take the subway to the gym, has an entourage of managers and trainers as does Phil. I remember when the movie came out, one of the forums was wondering why they left out Kai's fiancé (who was apparently very involved) and new trainer.
These things were left out because it didn't support their created character.
***Also think about this***
Any real documentary about Kai would very likely have some very disturbing content.
