On the 'sport vs family film' point, surely the big thing about (televised) sport is that it is one of very few things where there's a genuine benefit in watching it live. The result is unknown, there's no script, and unlike a film (or sitcom, documentary, opera, etc) it's not the same if you watch it later. There's a shared experience in watching events unfold that doesn't apply to most things on screen. That's why I'd argue a live sporting event can take priority over a family film (that would be the same if you watched it tomorrow). You could, I suppose, make a similar case for (some) reality TV, Eurovision, the lottery draw etc - anything where the outcome is not predetermined.
That said, while I would make that case for England's games (since I support England), I wouldn't bother for Spain vs Denmark last night (not Spanish, not Danish, not all that fussed about the outcome even if it decides who plays England next).
Random question: I know, if I wish, that I can watch the whole game after the event and, if I organise myself, do so without knowing the score. Therefore the action unfolds, for me, in the same real-time unpredictability I mentioned above. So why does that never feel the seem (used to do this sometimes when living overseas and my team's game was at an inconvenient local time, rarely got to half time without looking up the final score and spinning on to the highlights).
