The presenter needs to be at ease in front of the camera, but most of all he/she needs to be a very good natural angler with a keen, yet quiet enthusiasm that comes over well on screen. Many programmes have had the right idea but were severely let down by a lacklustre front man.
I have to say that I prefer the rose-tinted view of "A Passion..." and series' in similar vein, but I'll watch anything as long as it's reasonably well done.
My favourite TV moment was supplied by John Wilson, in the form of a boomerang-shaped pike that flapped free of his grasp and smashed his rod in two, with John exclaiming, "Well, that takes the bloody biscuit..." to the sound of the lake's duck population "laughing" in the background.
