Do admit the time flies very fast, but that doesn't mean it's a bad thing. If anything, it makes the show much better.
If the show leaves you wanting more then they are doing their job right, when Smackdown ends you come out of it not only satisfied that you watched a good show but it leaves you with that hook to come back next week. Raw lacks that and I'd say its one of the lesser reasons with ratings not only was the show you watched not very good but what makes you want to come back next week? The end of the show just kinda happens.
