This rating is for all 4 seasons. Overall, the show is great for everyone in the family. It's entirely innocent, full of good morals, humanity, social awareness, kindness and love. It has moments of real humor that made me laugh out loud. The only reason I took a star was one season where Christians were genuinely mocked while pagan beliefs were held up as the 'correct' way of worshipping. The church and those in it were held up as ignorant, shallow, uptight, ineffectual and lacking in human kindness while pagan beliefs were shown to be lovely, humane, magical, effective and above all, the most moral thing people could do. The message got very preachy in one season to the point of discomfort. I almost stopped watching, but I'm glad I didn't. The show corrected itself and the insults toward Christianity ended. The finer points of the show endured to the end. All in all, this show greatly entertained me for four seasons. One of the finest shows the BBC (or anyone) has ever made!
