What happened to smart advertising?

For a television advertisement to be effective, do you need to lay out everything for the viewer and make it obvious? Or, is an advertisement more memorable if you let the viewer connect the dots themselves?

Wind

People

Did they engage you? Or should the advertiser just have gotten straight to the point?
