Death Note
It is good for a good while but after.. you know what happens.. I was so unmotivated I genuinely took over 3 months to finish this. Plus the ending wasn't great to me. Throughout the entire show, they prove the lengths he was willing to go to as Kira but suddenly he didn't think about the chance of Near switching both notebooks.. yeah no way. Plus so many characters got introduced and so many felt like they didn't get a true story and it hurts me.. The first 20 episodes or so we're amazing and I was hooked! I wish it could have stayed that way the whole time.
(this is longer than expected)
