I haven't read your whole post yet, so I don't have any comments about how our TV networks work. From the length of your post, I have a feeling you've covered everything.
I would, however, like to comment on
Keen Eddie. I have to say the writing is wonderful, I love the way it is shot, and the direction is great. Basically, I love it. Of course, because of my luck with TV shows, which is that every one I've ever took a liking to gets cancelled, I also hate it, just in case.
Oh, and yes, it is shot entirely in England, BTW.
Anyway, I just wanted to chime in on the show itself, it's my new show for Tuesday nights.
