Seeing a movie where they flip in a practice dummy and actually make me feel like they broke ribs to make it happen would be legit.

If the ribs aren’t bending, ain’t no way the heart is pumping!

Also having the CRP patient be absolutely trashed afterwards. If you’re getting CPR, it’s cause you dead, and they are trying to bring you back to life by beating life back into you. You were dead, then got probably the most painful beating of your life. The rest of the movie should be you recovering in a hospital.
