I haven't seen all of the HBO series, but IMO The Wire was the very best. (I am talking series, not single season mini series like Band of Brothers.) Well, my friend HAS seen every HBO series, and he also thinks The Wire is best.
Galactic is funky stuff, I have a disc my friend burned for my many years ago.
So I went to see how much this show will cost on release, and it looks like season one is $55, ow. I guess I have to wait for Netflix to carry it. I've never heard of this show, thanks for bringing it to attention!
