Rather that push my favourite show/novel/TV series, I take the liberty of proposing an assessment code which is not only for Americans.
1. Thou shalt not compare books with movies, ever;
2. Thou shalt not compare movies with video games, ever;
3. Thou shalt not vilify fantasy/hard SF/vintage SF/alternate history, etc.;
4. Thou shalt not believe that the inordinate passion for vampires/demons/supernatural horrors extends to countries which are far less religious than the USA;
5. Thou shalt not acritically judge any prequel, as so far, in most areas, from Star Wars to Star Trek to Caprica, they were chemically pure drivel.
And, to prove that human beings are illogical, here I go now providing contradictory advice.
Read books like "Twister", written by a real research physicist, if you want to read very entertaining hard SF, not Greg Bear, not Isaac Asimov.
You will instantly see the difference from folks like Asimov (a biochemist) who had (forgive me...) a manifestly insufficient grasp of physics.
Even I, research physicist, was always underwhelmed by his forays in areas he knew precious little about (a PhD in biochemistry does not make you an authority on particle physics or quantum mechanics or a number of other things).
He even proceeded to top up his display of ignorance by publishing divulgative stuff on any possible subject.
That he is still considered a saint by a sizable community makes me wonder...
And to finish in beauty: casting a Scotsman who was famous for roles as e.g. the lead male actor in The Full Monty was not just catastrophic, but plain dumb. This contributed greatly to transform a would-be SF series as Stargate Universe into a boring reality-like show, eventually killing (deservedly) the show. Just like dreadful Caprica.
Should I be so dumb to want to watch a reality, then I will go for the real thing, not for an SF travesty...
