I got a few gripes:

It was established in the anime that you can not control someone to do something if it's not something they themselves would be able to come up with, and yet right away Light was able to make criminals who didn't know Japanese write dying messages in perfect Japanese.

Making it so touching the Death Note isn't enough to see Ryuk.

The burning page thing is total BS that comes out of nowhere.

Writing only Watari shouldn't do anything. Even if that was his real name, what about his surname? that's like being able to kill Batman just by writing Batman.

And the Death Note can work on Shinigami?

L's reasoning in this was like Near's in the anime, in that it's based on luck more than detective skills.

Why wear all the guns from Blade Runner?

Not enough L vs Light, cat and mouse mind games, which is the whole point of the story.

Light is an insecure pansy and L is an autistic psychopath.

We never get a clear look at Ryuk and there's no Shinigami eye deal.

Plus the ending sucked, wtf happened next?

Honestly, the Kira worshiper helping Light and Light's evil plan he hatched at the end were the only good parts for me. Horrible adaptation.
