I watched Utopia & liked it quite a lot. The first series was the best, had enough intrigue & weirdness quotient, the characters were good. Something about the way it was shot was different & interesting, colours accentuated, or maybe that was the drugs I was on. The soundtrack was good too as I recall.
2nd series not so good, can't remember much about that, even though I watched it. As is often the case, the writers find it hard to keep the thing going when required by popular demand.
