The document discusses different methods used to collect audience feedback on a documentary: posting it on Facebook to get friends' reactions; an online questionnaire with questions about the documentary, print ad, and radio ad; and filming a family watching and then interviewing them. The main lessons learned were that Facebook feedback lacked criticism, the questionnaire clarified strengths and weaknesses of each part, and filming reactions provided spontaneous first-hand views of audience response and which specific moments elicited reactions.
