This is an imdb review that echoed my sentiments:
"First of, I made an account at IMDb solely so that I could submit this review.
Utopia is exceptional. It is a masterpiece. It gets 10\10 from me.
I won't explain what Utopia is about because I don't want to give any possible hint of what is to come, so I'll describe it by comparing it to other things.
Buy the DVD or download the show and your life will get.... stranger. Its rather unsettling how Utopia gets under your skin.
There are a few television shows that share some similarity to Utopia.
For example, if you enjoyed Fringe, the X-Files, then you'll be quite at home with Utopia's paranoid wanderings.
So then you cross the weirdness of Fringe and the paranoia of the X-Files with the violence of Kill Bill and the action\suspense of the Jason Bourne series.
Now cross that already bizarre hybrid with a series of scientific TED Talks given by Joesph Mengale, yes, the Nazi who chopped countless pairs of twins to pieces for the greater good.
I'm not sure which is more bizarre. That description or that incredibly, it works.
However Utopia is much, much darker than any of those. It is the darkest TV series I have ever seen. It also as others have said, feels very real.
A note of warning. When I said Utopia was dark, I was not joking. If you suffer from excessive anxiety or you're squeamish, then do not watch Utopia. Because this TV show is nothing like you've ever seen before, it will affect you. You will be thinking about the themes in it long after you've watched it.
The violence in Utopia isn't actually that strong at all, most of it occurs off the screen. But the intense atmosphere of paranoia which accompanies it makes it brutally real.
On the other hand since the governments of the world have apparently taken a leaf out of Utopia's manuscript lately with regard to surveillance, Utopia could well seem prophetic in a few years time. This really is a TV series for 21st century of flying killer robots and universal surveillance.
The Sopranos changed the way I thought about television. I thought television was for lightweights until I watched The Sopranos. It was like thinking books were mostly about erotica and then coming across Shakespeare and entering a world full of subtle complexities on a bunch of levels.
Utopia is nothing like The Sopranos. But the way it'll change how you view television is very similar.
Just one last thing. There is an American show called "Person of Interest" or something like that which has similar themes. Watch this instead.
In a word: this is intense. "
It also has one of the strangest soundtracks you'll ever hear. Listen to this:

Warning: Do not watch if you are especially prone to paranoia, depression or anxiety.
