I've personally determined that three factors must be firmly in place for a movie to be a good movie; they are: 1) Good direction; 2) Good acting; 3) Good writing. Imho, without all three of those (lighting, editing, costumes, various kinds of effects, are not required, though they are handy) all movies are failures in terms of art.
No taste for trash? You mean you can't just sit and enjoy some sleazy 70s grindhouse, or a Roger Corman production, just for gits and shiggles (and without the MST3K bots crackin jokes at the screen)?
