TV doesn't get better than this for the Sci-Fi fan with a sense of humour. Not everyone is going to "get" it (there are actually some jokes either too highbrow or too nerdy even for me) but for those that do, it treads the multidimensional tightrope of sci-fi homage, and both silly and scientific/mathematical humour with unparalleled skill.
A labour of love by the creators, and it shows.
