Finished it a while back, great series.
Favourite character and favourite 'character to choose where you want the series to progress' is Near. Something about his character is just likable. His theories and abilities are interesting to watch as well as his personality. I enjoyed the side plot with Mello and himself and how they saw each other, how it ended.
Hmm, I think a more personal reason as to why I like Near is that he seems like he has Asperger's Syndrome possible traits similar to my own.
Too many people hate Near's character... I never saw him as an L 'copy'. Ryuk is a favourite of mine too...
I picked up the first live action movie too. I got a special edition version and to my surprise, the presentation of the DVD came like the actual Death Note which I thought was a great touch:
