I just got the DVD set of the BBC's production of Hitchhiker's Guide To the Galaxy. If you have the means, I strongly suggest picking one up. I was a huge fan of the series of books, and the 6 episodes really do the books justice. It is almost how I imagined it, but with the cheese ball BBC production.
Nevertheless, why do most BBC productions that I have seen kick ass over US productions? By and large, television in the US is crap, and the shows that I have seen from the BBC have been really well written and interesting.
