> If a person hasn't seen the film by the time it leaves theatres all together, they don't care.

That's really easy to say, but here in the UK a films release can be delayed by months, in other countries it can be much worse, especially if it's got to be translated. I've had stuff spoiled for me this way and I watch 100's of films a year, I actually don't generally care about spoilers either, but it still sometimes leaks through.

When I talk about film I tend not to talk about the details of the plot, mainly because when I start reading a review that's just a detailed summery, I stop, because it's not interesting. Outside of that I think pop culture references are kinda dying, the contexts you can use them in are increasingly limited and there's just less and less stuff that 'everyone' has seen. Right now there isn't a Game of Thrones level thing to spoil, so the conversation seems a little redundant. But just referencing things that need a spoiler kinda still seems childish.
