Hi - yes, I've been reading about this and it looks good. I adore that part of Wales, it is utterly beautiful and very atmospheric. However, like Biyani, not sure how to get S4C so may have to try and watch on catch up - we are quite far from the Welsh border now, so not sure how far it is broadcast.
Hafod Hotel looked very imposing - and I've never actually seen the falls so that was good. I was interested to see that the writer was someone who'd written quite a few episodes of the Heliwr/A Mind to Kill series I worked on years ago (the original of which was filmed in Aber in the early 90s). I think Richard Harrington is a bit of an improvement on old Philip Madoc .
