Is there any book/movie/show etc where armor is actually useful? Because we keep seeing guys dying even if they are wearing full plate armor by little more than a wooden stick poking their chest, figuratively speaking. Not a spear, a wooden stick.

The armor we see in entertainment seems to be made of butter rather than steel it seems. Why would you even bother wearing it? Granted in video games, it seems to work.
