I was nearly very unhappy when, at seven o'clock on Friday evening, we had a power cut .... fortunately it came back on again forty minutes later!
Overall I was impressed and am sure the majority non-caver audience will have been very imrpessed indeed. I am a non caver and kayaker and found I empathised with the presenters much more and, therefore, enjoyed them more from that point of view.
I agree with everyone else that the filiming was superb and the choice of caves was probably a good one (although I am convinced Main Shaft would have been better than Titan from both a visually stunning and scary point of view).
What I found a real shame was that they seemed to have too little time for 4 caves and, therefore, were forced to spend all their time focusing on one major (scary) aspect in each cave ... Cheese Press in Long Churn, Sump in Swildon's, Long Crawl in DYO and the pitch in Speedwell-Titan. The result was that the viewer received a very skewed impression of what caving is like. I understand why they did it, but I'm not sure it was right to do it.
Despite all this, though, I'm not sure it will have put off any potential newbies who are likely to be taken by caving as a sport. Let's face it, if the idea of a crawl and a squeeze put you off, you're probably not going to take to caving in a big way beyond the first few trips anyway. To my mind anything showing caving in a quality, prime-time format (as this was) must be good for the sport. Well done BBC, Gavin and everyone involved!
Finally, my Dad (who is also a caver) agrees pretty much with Andy Sparrow. He thinks it was by far the least good of the three in the series.
