I just saw the trailer you linked to. Seems a lot of testosterone. But I do not dismiss the notion that dogs form packs and hierarchy, even though these are loose and can change.
We mostly use common sense and see what works. Our family is the pack, for all of us, not just the dogs. And there are fairly clear rules on what behavior is acceptable. The dog has been taught good manners, sit and wait till we walk out of the door before running out. Similarly, sit in the car and wait till we let her out. Also, sit and wait nicely for food. Finally, the furniture is pretty much out-of-bounds and she can come up only when we ask her to.
Don't see anything wrong with it. We have a secure, happy dog who never growls, snarls or bites at us or other humans. She knows how to ask for things nicely and if she is uncomfortable or hungry, she lets us know in non-aggressive ways (e.g., she pushes her food bowl to me when she wants a snack). She does growl at other dogs, but rarely and usually when the other dog is being very aggressive.
To me, there is no point is having a rigid adherence to a certain training approach. I just say, follow the middle path and observe your own dog and what works for them. I can see with our nine puppies that they each have their character and different incentives and corrections are required depending on the personality of the dog.
