How to rig a face for animation

When I was first learning to create character rigs in Maya way back in 2002 while working on the Playstation 2 title Superman: Shadow of Apokolips, the rigs we used weren't most efficient, and Set Driven Keys (SDKs) were used for nearly everything. 

The hands were driven by them and so were the facial expressions, in fact nearly every control had some sort of SDK involved. Don't get me wrong, the Set Driven Key is a powerful tool in Maya, but you might have to plough through a load of Maya tutorials to figure it out. It can be time-consuming to set up, and is easy to break and a pain to fix. Plus, your scene size can end up bloated by animation curve data.
