As good as the pilot "Walking Dead" was, I stumbled upon the mini-series "Dead Set" on IFC and I liked that better. Now it does make it easier to like something when you can see the whole thing in one sitting as opposed to just watching the pilot but "Dead Set" was a great zombie story. It's got some funny moments but definitely isn't a comedy but it's about a zombie outbreak in London during eviction day on Big Brother. The cast and some of the crew take refuge in Big Brother house and try to figure out how to survive. The thing I like about it over "Walking Dead" is that the reality TV angle kind of adds a fresh take on the zombie genre. "Walking Dead" was really well done but there was a faint "Been there, done that" element to it (Especially the opening which reminded me a lot of "28 Days Later")
Below is Episode 1 of "Dead Set".
