I first watched this show about 4-5 years ago, I had bought it on DVD because I had heard such great things about it. I was amused, but slightly disappointed. It didn't immediately appeal to me. However, about 1 year ago, my friend convinced me to give it another shot.
When trying to describe how this show is produced, it is impossible not to contradict oneself. The point of this show is to laugh at the shoddy production, writing and acting. However, the way this show is acted, written and produced is, for me the best, the most observant, yet ridiculous, that I have ever seen on British comedy television. My favourite example of the writing has to be in episode 3, 'Skipper the eye child', when Rick Dagless m.d. (Garth Marenghi) says:
You know what Sanch, you can dissect a heart, but you'll never know what makes it skip a beat
This programme, for me is pure genius, because Matt Holness, has really nailed the genre on its head. This programme not only makes me think of and laugh about shoddy horror shows, or appalling writing, it also makes me think of the times that I thought that I was a talented writer when I was younger, and wrote lines similar to the one above, feeling very proud of myself.
This show should not be missed, and if you were unsure about it the first time, give it another shot. You will not be disappointed. It comes second to Arrested Development for me, and that is the only show that I would ever rate 10/10.
