When I started to play poker some three years ago I watched few videos but soon realized I do not want to watch them any more regardless if they are angry or in their average mood.
They may be intelligent and hard working and I assume you can learn a lot from Phil Hellmuth's books, but what can you gain from watching him in the action ?
If this is your definition of fun let be it, but I prefer to watch the youtube kittens instead.
One can argue that you can learn some intimidation techniques there, but again, I prefer to learn from real professionals.
