The problem with that phrase is that people will often use it to describe things that they just don't like. For example, the whole idea about having too much detail. There can't really be too much detail if the writer is good enough, although I guess some people just don't like it. I would say that something is poorly written if it doesn't flow well or fails to absorb the reader into the story and the character's world.
Aside from this, there are techniques that really shouldn't be employed in writing. Firstly, the ones like Chairman Miaow mentioned about crime thrillers. You can't create a mystery by just withholding information. That's cheating. Then there are things like writers using a lot of different words instead of "said" in dialogue.
Anyway, this is really too wide a topic. Maybe you can find a book that details those bad writing techniques that should be avoided.
