Yeah, but that was at a point where Light was already at his end anyways. He would have been imprisoned and had led a miserable life, blindfolded and isolated, so that he can never become Kira again.
In a way, it was nice for Ryuk not to wait until he would die naturally. ;P

I see. So I didn't remember correctly what happened in the movie.
That just means that they never got their desired end (L and Light both dying at the same time more or less) - if my assumptions concerning Reversi (Bakuman) were right, that is. ^^;

I still think the manga is the best version of all in existence. I hated the fact that they made some stupid additions in the anime before L's death ... like L out in the rain and then even wanting to wash Light's feet. T_T .... WTH?? ....
