I was watching the programme as background noise, while reading a newspaper. My ears perked up because the topic is of interest to me. My continuing or not continuing to watch I think is irrelevant.

I do not watch with an intent to nitpick but yes, I do notice errors and malapropisms. It is like finding a little piece of gravel going crunch between your teeth, as you enjoy a good caramel custard. Very annoying and distracting.

Going by this morning’s (3rd Nov) Newswatch, plenty of people keep watching but point out mistakes too. So plenty of viewers notice _and_ take BBC to task.

NB: I cannot resist so I must say this. I apologise if you are offended.

All the apostrophes you use are redundant. You intend to write plurals; but you write possessive case of those words instead. So in the above note, malapropism’s, cliche’s, metaphor’s should be set aside and replaced with malapropisms, cliches, metaphors respectively.
