I can't remember if I mentioned this before, but since the news has been posted up on the official site to remind me thought I'd give it a mention. The original series is being repeated on AT-X starting the 28th of April:
The second episode is scheduled foth the 5th which means, if they keep showing an episode a week, that they will show the last episode
some time around the end on the 6th of October by my reckoning. The optimist in me says that, like the movies and the box sets, this resurgence of interest in the original series is leading up to the broadcast of the sequel, but it is fairly safe to assume that this is not going to happen till after the original series has finished it's re-run at the earliest.
