I'll keep it short. If you're expecting 101 minutes of gorgeous majestic landscapes, fascinating wildlife and cultural history, you'll be disappointed for at least half your time. Yes there is some of that, but there are equal amounts of inexplicably mundane chapters, such as guys driving trucks (as if we can't see that anywhere in the world) or guys navigating oil tankers (as if we can't see that anywhere on the high seas) or guys wrestling cattle for sport (as if we can't see that anywhere in Texas). If I haven't been clear enough, I'll spell it out: they spend way too much time documenting things that are not particularly Australian other than the accents. After a while it becomes an annoying diversion from the otherwise well-done segments about the outback, the distinctly Aussie wildlife and the stunning red landscape that you can't see anywhere else on the planet.
Oops, let's get back to a guy driving a truck. Or a guy fixing a fence. Or a guy talking about oil tankers.
There were ample segments about the indigenous aborigine people, but at times it felt contrived because of the ultra stylish camera work and perfect lighting--definitely not convincing as a documentary as much as a staged production. And you may find yourself furiously annoyed at the "Matrix" camera clichés; you'll know it when you see it, when the camera is gracefully floating and then BAM suddenly it goes fast motion and then BAM back to slow. I lost count how many times they did this. Around once every 3 minutes.
Also the music is annoyingly loud which plays poorly against Russel Crowe's whispery mumbling as the narrator. His subdued monotone is fine during scenes with no background music, but when they juxtapose some annoying "Dateline" jumpy music score, it's really hard to follow what he's saying.
Despite my overall negative reaction to these flaws, there is some fabulous photography of the landscape, if you skip through the people segments. Not much wildlife unfortunately. But lots of overhead helicopter/drone shots of the terrain give us what we came for.
