Review of Durarara!!

So I just finished Durarara!! and I have to say it was insanely good. The story was great, and I loved all the characters. And I loved how the first couple episodes seemed rather random, but helped develop an understanding of some important characters. The one thing I am disappointed with is how they left Celty(sp?) and her head. Maybe it was more symbolism then anything? I must say my favorite characters include Izaya, Shizuo, Erika and Walker. Overall it was a fantastic anime and I feel almost everyone would enjoy watching it.
