I watched the movie twice, striving to make different choices on each pass. Neither pass shed much light on the apparent duplicity of Stephan's parents, the "Truman Show" element could have been further developed. The action Stephan undertook to "successfully" complete the game to the satisfaction of the kid reviewing games on TV and led to his undoing, as he descends into deeper issues of mental health was the most developed element of the otherwise fractious plot. This raises the spectre of what awaits the next developer to attempt to bring the Bandersnatch video game to "life".
I am not a video gamer, but i have a healthy respect for the creative and technical skills required.
I appreciate what this movie represents for the entertainment industry, and look forward to the next interactive effort.
