the ending of the finals

One thing that really irks me about the ending of the Love Island final, and you can say the same about any reality show really is when they announce the winner, they are always celebrating and the host is trying to get a conversation with them before they cut the show but because they are celebrating, the chat never happens. Original series, the choice was always rushed because of this. I dont understand why they stick to their schedules so much, why don't they just schedule the show to finish at 10.45 for example rather than 10.35 so that final bit isnt rushed, are people really going to complain because family guy isnt on at 10.35, no of course not
