Just watched the whole show... (SPOILERS)
(SPOILERS BELOW) too lazy for tags... Apologies in advance the lengthy post.
Thought it was really great overall. There was a lull after Misa and Light were being held and lost their memories and after L died. The majority of the show was excellent though. Loved the portrayal of Light and L's "friendship"/rivalry, didn't really get that same sense with Near.
I guess I'm a little conflicted about the end. Part of me wanted to see Kira get caught (his actions were dispicable) and another side wanted to see Light win (he was so damn smart and sometimes it's fun to root for the bad guy). I would have been satisfied either way, I just found it hard to believe that Light would fail so miserably after having been so careful for 5+ years.
There were so many ways for him to win but only one way for him to lose. And he lost spectacularly. I will admit it was fun to see him squirm and panic, even if it was out of character. I guess I was expecting a brilliant counter move, since he always had one. I can picture a scenario where he would anticipate a fake Death Note and have X-Kira write Light's name down and just make the time of death 1 second before his life span was over (write the life span in invisible ink?) and implicate Near by not including his name. Or make a deal before the meeting for the Shinigami eyes. Or even if he was caught, just admit to it and walk away. The SPK and taskforce don't believe in killing and Kira's influence might have been great enough that he could have gotten off. But he had a meltdown instead because he lost. I guess they wanted to show how his arrogance had caught up with him.
I also wonder what will happen to Misa, now that she has no memory of the Death Note and an unnaturally long life span thanks to Ren's sacrifice. And dammit, I wanted to see what would happen to Light when he died since he can neither go to heaven or hell.
