The Authority is pretty good, though it does suffer from the "Lensman" effect in later episodes - everything gets more and more over the top on a bigger and bigger scale... If you enjoyed The Authority, Andy, may I suggest you also check out Planetary, which is set ( sort of ) in the same universe and is, if anything, even better, with some amazing artwork and cracking writing.
