I thought of Death Note as an intelligent anime. It was awesome to Kira(Light) and L go at it. I mean each episode was like they were playing a strategic game of chess.
However, the only thing I didn't like at the ending was...
Light cracked... I mean I sat in shock as I couldn't believe that Light was reduce to a lunatic. I should've seen it coming but still to see him reduce was sad. IMO...
Though was also one awesome thing about the ending...
God... I can't say his name but the cop who was always acting goofy and naive... He truly stepped up. That was the best part of the series.
If you're into this kind of anime then I say you should give it a try, if not then I think you should still give it a try.
