Yes, this. I'm a huge Eurovision fan and the amount of complaints from people who aren't interested about it taking a number of hours of BBC1 over one week of the year is insane. (Yes, I know they also have some build-up on The One Show and chat shows, but these are varied magazine-style shows anyway, with no set formula or content).
Every single year, the utterly predictable "It's a load of rubbish, so they should stop showing it" - along with the people who share their incisive 'knowledge' that "it's all political, you know", because they once heard somebody else opine that 35 years ago and think it's an intelligent 'gotcha' comment to repeat.
Sport - especially football - dominates the schedules for months, and frequently disrupts other schedule staples (last year, the '6 O'Clock News' was on once at 1:30pm, because of the football). I can really think of nothing more boring at all; but I realise that the telly is there for everybody and not just me, so I (grudgingly) accept wall-to-wall football for weeks and weeks; but don't you dare come after our one-week treat and claim that we shouldn't have that either.
If you hate it, fine; don't watch it. But don't assume that your preference is all that ever matters for all of us.
