i've been talking about this a bit with Jossalin and i thought i would expand on something i brought up then in her actual discussion thread.
there are things on TV which we don't like, and there are a whole load of things on TV that i think can have a negative effect on the viewer, especially if the viewer isn't informed, isn't aware to the full extent that they are watching a manipulated version of reality made with an agenda in mind and, for some people, this can be extremely harmful.
but there are also things which are on TV which i think we benefit a great deal from, things which can enrich us culturally, make us more informed and more aware of the world around us.
the example I gave Jossalin was Adam Curtis' film 'The Power of Nightmares' which charted the rise of both Western neo-conservatism and fundamentalist Islam in the latter part of the 20th century.

i have also since thought of something else as well, which is the Life series of natural history films made by Sir David Attenborough.
Both of these were amazing, informative, eye-opening series' of documentaries which were shown on main UK tv channels. yeah, sure, the schedules are cluttered up with terrible reality TV, biased news, celebrity-obsessed nothingness and all manner of other crap... but occasionally something comes along that uses television to contribute something to our culture which deserves to be noted.
