My memory of Jack Hargreaves was he did not catch much, often blanked, whether that was incompetent or just picked days they were not biting I wouldn't know. The joy of him was just watching someone who was at complete ease in front of the camera and his love for what he was doing, But his out of town series was about all things countryside related with 15 min fishing slots, I don't think he was trying to prove he was a great angler which is another reason he was a pleasure to watch. I am trying to imagine him shouting and clowning about but it don't work; he was still the best for me. I wonder what he would have made of commercials, I reckon he would have just taken them in his stride..
I remember that Crabtree series where the bloke was teaching some girls to float fish for barbel with great big sausage sized baits, he kept telling them to strike as soon as the float moved instead of waiting for the barbel to get a proper hold of the bait and they never caught a fish, I kept thinking surely he was going to catch on what was wrong but he didn't, I don't know if he is incompetent but I found it frustrating to watch..
I would like to see another angling program where you were just taken fishing for the day suitably condensed, warts an all but where the presenter was not irritating, Jack Hargreaves could not have been irritating even if he tried, or maybe he could to some because we are all different but I miss his style of presenting in angling, he was never trying to be the star of the show, he just was.
I don't think modern presenters are incompetent, they can show the methods, ways and catching fish well enough but portraying that other-worldly charm of fishing is often missing.
