Paranoia Agent

Not too long ago I was introduced to an anime called Paranoia Agent. At first I thought it was bizarre and didn't quite understand it, but a few episode in and I was hooked. Has anyone else seen this anime? What did you first think of it? Were you able to get to the end of it? Did/do you have a favorite character, a favorite episode?

Personally, Maromi is my favorite character, she's just too cute. I don't really have a favorite episode, but it's certainly an interesting series.
