Almost every sort of film, IME. I can hardly recall a film that 'lectured', if we mean the same thing, and it would be panned if it did.
For one thing, if the filmmaker can't convey things without lecturing, they are in completely the wrong job. Does a painter have to add call-out boxes with labels? Second, they almost never have a specific message, but depict the world - art holds a mirror to the world (very generally speaking).
