Two thoughts, though: firstly, science fiction writers are always portrayed as loners in fiction, with Tony Leung in 2046 playing perhaps the loneliest of all. Here John Cusack’s character is doubly alone, having spent his own childhood inventing fantasies, and more recently become a widower. I don’t think this reflects real life, the few sci-fi authors I know or have met seem to be pretty gregarious types.
Secondly, where did all that Polaroid film come from? If I’ve read one blog about the artistic merits of this obsolete photographic format I’ve read about a billion, and every single one bemoans the difficulty in obtaining film stock. There’s even an open-source style project by Polaroiders to invent an alternative. Yet a child in a care home is apparently able to score an unlimited supply: someone should check out that child’s eBay account.
