That's a very blinkered attitude, if I may say so. Most TV channels have their quota of rubbish, perhaps ITV more than others - I don't know.
I choose my TV watching by possible interest in what is listed and NOT by what channel it may happen to be on.
I gave up on Corrie over 18 months ago and have also stopped watching the likes of BGT and X-Factor and may well decide not to watch Strictly Come Dancing anymore. Most of this type of show go on for far too long and many long running shows should be axed IMHO.
