My only worry would be if Yates came along and made a blockbuster with a completely different take on the character and format I didn't like, and BBC Wales decided to drop their current production to make something based on the movie.
That's what I'd be afraid of. Especially if it's a big moneymaker, telling BBC Wales to make the show more like the movie (assuming the show continues at all). After all, why have the silly old tv show when it's clearly the movies people want to see?
