The only issue with wall/ceiling speakers is that you greatly limit the arrangement of the room. If you plan to build a theater that doesn't ever change shape (furniture, equipment, etc), then they are a great way to keep speakers off the floor and more or less out of sight. Many times they can sound very good...depends on the installation, the source of the signal, and the quality of the components. You may want to play with different arrangements before running wire and/or setting speakers. Good luck!
