Other mistake: When Jaden and Syrus enter their dorm room, the curtains are closed, but this doesn't affect the lighting at all. The light isn't switched on, but the room appears exactly as it would if the curtains were open, without appearing dim or darkly lit, and the lighting doesn't change once they open the curtains.
