I have watched pretty well all the previous series, and find it generally interesting, but two thing irritate me.
The first is the way a particular storyline is repeatedly broken up into little pieces. Now I know that TV producers these days seem to think that people only have a 10 second attention span (and need to see things at odd angles and zoomed in/out rapidly), but I would suggest that is not the case for viewers of this program.
Secondly some of the content leaves much to be desired, and gives a rather false impression of waterways use. In particular was the story of the hen party, which seemed to concentrate on how stupid the girls were. No doubt they were nowhere near as bad as it came across, but I suspect selective editing was used to give a more "fun" (!) story. The impression was given that it's ok to go boating in high heels, it's a bit of a laugh if you crash into other boats, and isn't it sooooo funny that we haven't got a clue what we are doing.
There is so much of interest on the canals: the people, the buildings, the engineering, the history and heritage, it is a shame that so much of the program is given over to trivial "popular" style broadcasting.
