Too much exposition does get clunky, but I do really like getting details that flesh out the environment. Working those details into the action seems like it works best.
Only sort of related, I do like to get a physical description of characters. I know some writers deliberately don't describe the character so the reader can make up their own images, but I find I keep waiting for clues to the appearance. I hate to start building my own image only to have something contradictory come along later.
