Good acting is good acting, in any medium. The foundations of good acting are all found organically in thorough training. The beginning actor learns the skills to pursue objectives, moment-to-moment tactics and actions, factoring in internal and external obstacles to those actions. They learn to inhabit an acute sensory world with physical and vocal skills, to be sensitive to text and subtext, to be a keen listener, to glean information from given circumstances and back-story.
