Wealthy/unlikeable vs Everest. How is this the first major motion picture about an Everest ascent?

Rating: 4/10 (23 September 2015)

First the good: The film had many captivating scenes of high alpine environs. The film makers did a good job portraying the rigors of contemporary mountain climbing, even if most of the high alpine footage was actually filmed 10,000 feet lower than suggested in the film.
Now the bad: The characters in the film were utterly unlikeable. These folks were no Edmund Hillary and Tenzing Norgay let alone Charles Bruce and George Mallory. Unlike early climbers, these TOURISTS had all the amenities they could dream of: lots of technical and logistical support, pre-set paths, experienced guides, etc. etc. How heroic is that? Furthermore they were all full of pomp and attitude, especially the men. The line "100% Texan, here" still rings painfully in my ears. I found myself rooting against the men on several occasions, especially near the end.
Now to address the elephant in the room. HOW IS IT THAT THE FIRST MAJOR FILM ABOUT AN ASCENT TO EVEREST WAS ABOUT THESE IDIOTS?
Please, somebody, make a proper film about climbing Everest, such as the ill- fated 1924 British Everest expedition. These were REAL explorers, not the guided tourists from this pathetic film. There is even wide speculation that the 1924 climbers, Bruce and Mallory, were actually the first to reach the summit, something films like to explore. They didn't have much technical and logistical support, and were reliant on early 20th century technology. Unlike the characters in this film, their story is actually interesting.
