Good ending. I think I somewhat prefer how Light died in the anime actually. Although, I wish Mikami hadn't stayed loyal to him in this version.
EDIT: I haven't actually read much of the manga, other than the first few chapters, some in the middle, and then the ending. I guess my one gripe about the anime's ending was that it did feel rather inconclusive. It didn't show what happened to the task force after the finale. But then, I agree with Tokoro that it might have been a good thing that they didn't end up adding that.
I think I'll try the one-shot out, since it apparently reveals a bit more about some of the characters.
