>> small number of writers or just one can lead to some very poor scripts getting made
You're right, but on the flip side it allows for new ideas, which are what the best TV shows have. I'll take a wide distribution of quality over everything clumped around the mean.
I still expect to see better, more original scripts from individuals compared with collaborative efforts. That's my experience from science fiction at least, where many good authors have paired up to write a book and it is nearly never as good their individual works.
You could be right about prejudices holding back the UK TV industry. I don't know much about that.
