i agree with ending it at L's death but IMO it would have been incomplete end ... in the end light had to fall no matter what.. i already said this somewhere, i feel makers of code geass might have learned their lesson from death note and avoided this route.. anyways only ending acceptable would have been L sitting things up like " if i die now.. its clear light is kira" .. or L winning but without some OMGWTF twists this one would have been boring ..Actually, if they ended DN after Light killed L, that would have been the ideal ending.
