What do you like about Ergo Proxy?

Ergo Proxy has been a popular cyberpunk anime since it came out. I've watched it twice now and I just... don't like it. It isn't bad, but I don't see the appeal. And I feel like maybe I'm missing something.

The first episode is amazing and sets up a really interesting world that I can't wait to see more of. It makes me think the series will be about hunting down a serial killer in a cyberpunk world, which could be really cool. But then they go out into the wasteland and I lose all interest. And then there's the game show episode and the "lost in an abandoned grocery store" episode and I start to question why I'm even watching it. By the time I get to the end of the series I'm just waiting for it to end. However, I'll accept the fact that maybe the issue is with me. Maybe there's some deeper meaning or symbolism that's going over my head and there's actually a deeper story I'm missing out on.

So for those of you who liked Ergo Proxy, what do you like about it? What do you think the story is trying to say beyond the surface-level plot?

Here's a trailer for anyone who hasn't seen it. You can watch the entire series on Crunchyroll.
