My wife and I saw it in Houston at the AMC Gulf Point 30. It was shown in one of the smaller theaters but was about 85% full. A lot of blue hairs, Tea parties I expect. I don’t think many minds were changed which is really what needs to happen for this movie to be a success. Having served in the Coast Guard in Alaska I enjoyed the scenery. Having been in oil and gas, I found the demonization of ExxonMobil a bit over the top. All in all the wife and I gave it two thumbs up.
It changed one very important mind over at Red State:

We saw it in Colorado.
The movie points out that the Valdez spill in 1989 was a transforming moment for Ms. Palin. She has no love for big oil establishment, but does have love for domestic energy production. So at best it's a love /hate relationship.
The most ironic part of the movie was all the time they spent on the natural gas pipeline deal. Kudos to her for getting it done after 30 years of discussion.
Then the project was withdrawn (I think) because so much gas is being produced in the lower 48.
