It's a new british show (BBC, though it can be, um, aquired everywhere :) that deals with Merlin as a young boy coming to Camelot. Only magic is forbidden at this time so he can't show anybody what he can do.

And then he gets told that his destiny lies with Arthur, only they had an interesting "meet cute" earlier and don't like each other much in the beginning.

The protagonists are young and the show is geared to a somewhat youngish audience - also the historical inaccurcies are ripe - but it's such goofy, wonderful fun. And Merlin and Arthur are such a sweet pair with their bickering and banter. For me its a great cheer-up show when you're feeling down.
