Slightly sleepy series that is moderately interesting but probably only if you're into politics. It's nowhere near as watchable as some other recent political documentaries like Hillary.
It would be unfair to call this a complete white wash, as it does reference some of the failures/disasters, but it definitely takes a very softball approach. For example probably 80% of the contributors are Bush insiders or extended family. It also sometimes has the feel of a campaign made documentary.
You'll probably learn a few things but this isn't anywhere near a balanced portrayal of the Bush family and their political impact. You will need to look elsewhere for critical analysis of some of the more controversial and/disastrous issues like 9/11, Iraq, Katrina etc. Even from a personality perspective you are left wondering how and why some of the family were either able to or interested in seeking high office...
