I think it was Pixar directors who ran a critique for their film had this rule when critiquing movies in development, they would offer pain points or problems (not solutions) - i.e. their feedback would be "I don't like the way this character meets this other character" and would not offer a 'solution' on how the characters would meet

I thought this was interesting - why? Because ultimately the director that was working on the movie themselves would know the potential solution the best. I think this also generally works great with engineering as well. As a manager, you don't really offer the solution, you identify areas that aren't working because engineers on the task usually know the system significantly better that you do the higher up you go

Yes!  
This is how Pixar solved what would’ve felt like a domestic violence scene in the Incredibles.  People who watched an early screening complained about Mr. Incredible being so aggressive toward his wife.  Storytellers might’ve cut the scene and lost some critical character development.  But an animator solved the problem using the elastic properties of elastigirl.
