I don't see what is so bad about it. It's about time Loony Tunes updates their characters to fit in to the 21st century. Personally, I feel, that the existing characters were going stale. If it is successful then it will be seen as a gamble well worth taking, if not then oops, but isn't that the whole point of a gamble.

It would be naive to think that all the Loony Tunes characters could stay in their predefined moulds forever, they have been evolving the characters over time and despite this being a rather drastic step towards the radical, I hope it pays off.
