the series has been, I believe, turned as successor of Dr. Who series and also contains humor and it is also in most cases rather always good (at least until shortly before the end of the second season - sniff, ... I think because the makers have made a mistake and is one of the reasons why the third season would no longer run correctly, and the series was canceled - well and up to the final end of the third season). But it is usually rather simple and linear, but as I said, quite nice snack.
