Some people are feeling nostalgic about the possibility of having to wake up early for the Japanese GP. I'm not too happy about the possibility of an early wake-up (even though it's better than a complete wash-out). But what's your preferred start time.
The typical afternoon slot is getting increasingly problematic for me. It's the best time on a Sunday to spend doing something outdoors and the 3pm race kind of splits the day. Morning race at around 10am would almost be better, you could still sleep enough and have the whole day after the race.
But my preferred time slot is evening. A race between 7pm and 11pm is ideal, I've had the whole day before it, then some fun in the evening by watching a race. Even 5pm would be better than 3pm, two more hours to do something before the race. And I can even deal with a very late night start, as long as the race finishes before 3am, I can live with it.
So, I prefer the afternoon races in the Americas. An evening race in Europe would do the same but will probably not happen. A night race would screw the visitors and series in Europe don't have such pressure to please the American TV audience.
