Well some movies are very hard to review without revealing any spoilers. I would say that yes it depend on the age of a movie or book to some extent, we all expect people to know how Psycho ends or that Dark Vader is Luke's father, however this also go only so far.

The way I see it it is difficult to talk about a film without making any spoilers, however if one is discussing major plot lines then it is better to use the spoiler warning to often than to little.

I also have to say that some people are very sensitive to spoilers and others no, and some considers everything a spoiler. Like I mentioned a joke in a horrible science fiction film once. Basically in the second Gor film Tarl and his sidekick come to this nasty old lake, there are skeletons laying by the side and the water is all but black and green. Tarl like and idiot go to drink and the sidekick says. "Do not drink the water!" Tarl asks "Why not." The sidekick then says. "Because it is poisonous!" I mentioned the scene to point out how stupid this movie get. Well one lady was very upset that this was a spoiler. Really, it like mentions a five second sequence which have nothing to do with the plot what so ever. So I told her that if she was so sensitive to spoilers then she should not discuss a movie online.

My point is that if you are discussing main plot twists and ending then let people know there will be spoilers, but anything but that flies, if people are discussing on a movie forum then they have to expect a few spoilers now and again.
