G.W. I would argue a fun read is a good book, and I do love some of the trash SF novels, but I get your point. I think the better term might be "inspirational". That would winnow the SF pool down! Something like
Dune is certainly inspirational.
And to pile on the pea brain point...Even by my very loose standards ECW is annoying and doesn't belong. Fiction, yes, science, no. I mean, really, couldn't they do re-runs of bad SF from the fifties? It would be a step up. I think the monster movies are pretty horrid as a group, but they, at least, technically make the cut

Wheel, the SciFi channel has been getting better pretty regularly. They still have some pretty bad things on there, but the Friday night line up is worth while. SG-1, SG Atlantis, Dr. Who (new version), BSG, and Heroes have all been part of the line up. Decent stuff has even made appearances on other nights...Eureka is looking solid.
