I think it would have made a far better film than it did a TV series. These days I am usually saying the opposite.
I was not a fan of the show, too slow, not well structured, internal logic and mythology too scattergun. There was a nice neat and intriguing plot in there somewhere that would have better suited the short format of a film, instead of the dreadful (leading nowhere) cliffhangers.
Like most of the shows I moan about, I moan because I am lamenting the loss of the far better show that it could have been. If it was total trash I probably wouldn't comment . . . I did actually watch the whole thing, which can be quite rarity of late.
