The only time where I was upset because of a game's length was for Star Wars: The Force Unleashed. It wasn't a bad game by any means, but when all was said and done, I clocked in 6.5 hours. I wasn't too happy about it, seeing as there was little incentive to even go back and do it again. With a length like that, I could have rented it for 5 bucks instead of purchasing it for 50.
A game can be short, but it needs to have a replayable element to it. Wario Land: Shake It! is a great example of this.
So I really don't have a preference, whether it's short and replayable or just plain long.
