As near as I can tell, it's still up to me what I watch or what my kids watch. Considering we always talk about stuff and they know where we stand on things, I don't worry about what a movie might say in terms of it's 'agenda'. I figure it's still up to me to help my kids process things and make up their own minds.
In the end, a movie is entertainment. If I've done such a lousy job teaching my kids that a movie can determine their politics, it's my own fault.
