Thanks for your very sensible explanation - I'm going to have to borrow for next time a non-techie friend of mine says something about a film that covers a person's life (so I get an expected eye roll or worse).

Reminds me of a guy who shot 1 second every day for a year to make a video. He ended up on Ted's main stage and ended up making an app.
