Not at all, in fact I think they are best that way. I said the same thing to flames and I'll say it here too. You can learn more about a character or story by the hardships, tradgedies and bad things then you can from all the descriptive words in all the world.
For example, you can say a soldier went through hell in war. Thats fine you get a basic understanding of the soldier, but if you describe his battles in all their gruesome detail you get a much better understanding of the soldier. Sometimes ya gotta write dark things to get a point across.
