Why are people dissatisfied with the ending of Durarara! ? I liked its ending. At least it ended without any cliffhang and IT'S A HAPPY ENDING!! Don't you guys like happy ending?

SPOILER ALERT!! Please do not dare read if you don't want to be spoiled at all.

I think we all wanted to see what Izaya wanted to happen, and see him as a great antagonist and what will happen to Selty and her head if reunited, because that'll be cool. What would Selty's head look like if awake?

But really, Izaya could've actually shot either Mikado or Kida to see how Anri would react, but I think Anri will immediately slice him if he does that and then such "war" with Anri wouldn't actually help with his plans. In the end, he did not succeed in ruining the whole Ikebukuro so no "great war which only he can fight" happened. In the end, all of the nice people helped with the mess.

But yeah, nothing happened much to the "antagonists". So, meh.
We wished they developed more: Shinra Kishitani's dad, Yagiri sis, Izaya, (I actually wanted to see him suffer and cry psychotically there was an opportunity for that to happen after Simon talked to him but he was just too stubborn for that) and some other characters (which are side characters) like Simon, Shinra, and Shizuo's brother. I also want to conclude that Saki is Izaya's sister (because I can see some resemblance in their eyes and hair) but he doesn't really care so much about her.

This anime is almost like how it is in real life, one will not see everyone develop because you won't be able to focus yourself on everyone, only to the main people in your life. So yeah, I liked how my favorite characters ended up. Okay, maybe almost everyone. At least they now continue having nice lives, with no one feeling miserable except Horoda and gang =))
