Make use of RedBox.com. Movies are only a little over a buck. If you create an account, you will receive notices of new releases and you can reserve your movie online and pickup at the nearest Redbox location. It works great.
One other think, most cable/sat companies don't advertise this but they have simple packages that do not include the alphabet networks and then you can build on this package with single subscriptions to channels The Blaze on Dish 212. :)
No, not just a personal boycott.

Limbaugh and co. might be good at this.
They could add a daily message - no movies in theaters this summer. Give Hollywood empty seats - and announce it well beforehand.
Do something else with the kids.
You can rent them all later anyway.
