Embodiments are described that enable remote and interactive access, navigation, and analysis of reactions from viewers to a media instance. The reactions include physiological responses, survey results, verbatim feedback, event-based metadata, and derived statistics for indicators of success and failure from the viewers. The reactions are aggregated, and an interface enables remote access and navigation of the media instance, aggregated physiological responses synchronized with the media instance, survey results, and/or verbatim feedback related to the media instance. This enables users to interactively divide, dissect, parse, and analyze the reactions as they prefer. This automation provides an automated process enabling non-experts to understand complex physiological data, and to organize presentation of complex data according to their needs so as to present conclusions as appropriate to the media instance.
