I'm not defending it, per se. I'm defending (for lack of a better word) the notion that somehow game length has any bearing on the quality of the game, RPG or not.
If your issue is the content, then I've already said that's more than valid. But you seemed to stress how long it took you to finish, as though that short game length in itself explained the lack of content that you felt was missing. So I took that to mean you were suggesting that it being short was the reason it was lacking. In which case I disagree. Short games can have much more, and much better content than longer games, and vice versa.
