With no TV I cannot judge what's being broadcast now but I recall watching the original Dibnah series on my parents' TV. Looking back, I do wonder if some of it was him playing, unwittingly or willfully, to the camera!
The problem I did see coming in was a tendency to use presenters far more than the experts in the programmes' topics. This crept into Horizon, which seemed steadily taken over media-studies graduate producers frightened to show what they didn't understand- the science they were paid to report at a far better level than the plastic-hatted whizz-bangery of Tomorrow's World.
The typical gimmick, apart from merely talking heads to save filming what they were talking about, was the over-used cliche of fingers flashing around a computer keyboard.
One of the worst I recall was an edition of some magazine programme in which were narrated a painting, a stately home and Swiss predecessor of our Tornado project. The painting and house were described excellently by professional enthusiasts – academics in such art and architecture. The locomotive though, was obviously only "metal bashing" in the media world, so let's send some slip of a journalist clearly out of her church-fete depth, who tried valiantly to tell us of the construction of a new, and (to her, never-done-before), oil-fired, steam-train.
Have things improved, or am I better off staying a TV refusenik?
