Final answer:
Shakespeare valued authenticity and believability in acting.
Step-by-step explanation:
Based on the conversation between Hamlet and Horatio before the play, it is difficult to determine Shakespeare's own thoughts on actors and the acting industry. However, we can infer that Shakespeare was critical of actors who overact and lack subtlety. In the dialogue, Hamlet instructs the players on the need for restraint and naturalness in their performances. This suggests that Shakespeare valued authenticity and believability in acting.
