Arthur's death shouldn't come as that much of a surprise, considering that that's generally how the story goes. But it won't necessarily be doom-and-gloom, so fear not! The way the legend mostly goes is that he ends up in Avalon, usually brought there by Morgan(a) at the end of his life, and then he stays there peacefully forever.

Besides, tragedy isn't necessarily a bad way to end, though I really think they're unlikely to end on a low point since it is, as you say, a family show. If they go down the Arthur's death route it'll still probably be a very hopeful, paradise-restored kind of ending with a tolerant and magical Camelot etc etc. They may even go as far as to twist the legend completely and avert the traditional ending, though I actually hope they don't. If they do a cheesy happily-ever-after cop out I think it'll devalue the show and the legend, so I still do want the Avalon route. With a redeemed Morgana.

I agree with you, though, I think there's a lot more to be told than can fit in one series. A hell of a lot of character development should be done before I can consider it anywhere near finished ;)
