I watched <i>Monty Python and the Holy Grail</i> with the boy when he was five. I wanted to make sure he would have a sound case for blaming me for all his adult problems later should he choose to.<p>On the other hand, we were in a clear majority for holding off on <i>Star Wars</i> [in which a whole planet of people are killed in passing] with great effort until he was six. Then we got an XBox 360 and he was shooting up things hisself anyways.<p>He seems to be turning out better than we deserve despite this. I suspect your best judgement will be fine.<p>Good luck.
