I think any programme about 'a subject' is subject to the same problems.
I'm sure anyone involved in airlines cringes at the easyjet programmes, I know I laugh at all the technology stuff on TV.
If it helps draw people into the world of vegetable growing then it is a good thing, once they are needing more detailed answers, they can search out websites like this!
I'm going to lock this thread as sometimes that is the only way!
