In fairness-
My recollection is that Sky paid some stupid amount of money to have exclusive rights to Star Trek
The BBC has brought out some of the finest new and original Sci/Fi that is going to be broadcast this year (Doctor Who).
All the other channels are doing a hell of a lot worse in terms of endless repeats. And while I wouldn't mind seeing the activities of Kirk and co again, I do draw the line at watching Voyager 6 times a day, it wasn't that good the first time around.
Don't knock the cricket- The test matches has been one of the most tense and exciting series I've seen for some years.
The best place for Sci/Fi at the moment is BBC7. There is a daily Sci/Fi slot at about 6, with the added bonus of being able to listen to them all again from the net. Some of the shows are old e.g. Journey into Space (6PM Saturday), Some is new, Doctor Who (6.30PM Saturday). But most of it is significantly better than TV's recent offerings
