One of the biggest sources of strain between the two, according to both of their books, was President Bush's decision not to pardon Scooter Libby. Cheney repeatedly went to bat for Libby in private meetings with the President and despite his admiration for the President, he felt somewhat betrayed by the way POTUS refused to fully exonerate Libby.
It's much easier to judge Cheney's public statements (in terms of whether or not he lied to the American people to gain support for the war). We don't need a documentarian to decide for us and, without having watched the show, I'm confident that the filmmaker doesn't expose any such thing.
The film does actually make a very compelling case that Cheney lied to the president concerning the legality of continuing their surveillance activities without the Department of Justice's approval. This was backed up by both Republicans and Democrats.
