Superheroes is a worthy addition to this well-establish genre, arguably re-popularised by Michael Moore in the 1990s. Filmmaker Mike Barnett's piece is a straightforward portrait of some of America's real-life superheroes. Other than the nicely done cartooning that marks the film's chapters, and some shaky 'ride along' footage, it is mostly talking heads, but no worse off for that. The tendency might be towards a first reaction of 'Really?' but, while there seem to be varying degrees of 'grip on reality' among the subjects, it's hard to argue that their intentions are anything other than good. There are a surprising number of participants, with a wide geographical spread, revealing the breadth of this activity, and almost all have a sense of their own limitations, operating within those bounds, and the law - setting their sights on realistic and attainable objectives. No-one here is going to affect the spin of the Earth or fly an atomic bomb through a portal in the space-time continuum (of course!), but it would be a cold person who was not affected by the good deeds that these citizens do. Their public spirit is admirable and it's to be hoped that there are many more people out there willing to step up in their own (quieter) way when evil rears its head in our communities. Barnett's film is well worth a watch.
