Gosh, depends. I have found it a mix with 5yo's. I am ok with drop off at 5 depending on location, type of party etc, but I have come across other parents who complained that parents dared drop off and leave at kinder age, so I think it depends on the parent group. Also depends on child. DD2 was better with kinder parties than with childcare ones with being dropped off.

We always cater for parents, we are out of town, so often it is not worth them leaving.

As for movies, I would pay for a party situation which I was holding.
