I think possibly everyone's expecting a little too much from the show, certainly in the timeframe they have for giving info out.
It's what, 23 minutes long? Less intro, outro, etc, you've got about 20 minutes to explain a key area. I'm assuming the amateur's spend all day with the pro, and so learn about what we expect to hear in the program.
It seems to be catering for everyone also, not just SLR or advanced cameras which have adjustable aperture and shutter speeds, therefore they have to focus on certain key areas which will be beneficial for everyone, even the person who's just got a P&S and is using it for the first time. What do they want to hear? Choose F16 to get everything in focus, or get that tree in shot it'll make the picture look better?
Unfortunately there's still the vast majority of people out there who still only own basic cameras, so they are targetting the demographic, not the keen amateur.
I have to say though, I was dissapointed with last nights episode more than the others. Even though there was more info in it, I've heard of the pro and admire his work so was hoping for a lot more detail. I felt it rushed and brushed over certain key areas. To me, Landscape photography is more technical than the other topics covered so far, and it fell way short. Would it have been so difficult or time consuming to say shoot in the golden hour, here's a shot taken at midday, here's the same shot at dusk, same location, see the difference? 20 seconds, instant impact and visual explaination so it sinks in.
