Remake isn't always a good thing. Its better they pay copyright to the original and create prequels or sequel to Death Note. An example L Change The World. They may as well do a story about B.B. or introduce Mello, Matt or even this A guy from the Wammy House. Or even at least introduce a very young Watari how he founded the Wammy Houses.
I would like to see maybe 'The L.A.B.B cases" made to an anime or a side arc that shows Mello Matt Near in wammys. I wouldn't mind seeing L change the world" Made into the anime. BUt they should at some point maybe make the "Dath Note anotehr note' a live action film. (COnsidering it would be easier then the previous ones I think) Maybe a re-make of the anime to fit more like manga? That might be a good idea..
