No, just no. A person is not rude if they are watching it for the first time. The others are only in self-imposed hurries, there is no etiquette there except to actually allow the first-timer to experience the story fresh. It's the seven who are being rude in that case if they can't wait the extra bit of time, not the one person simply because s/he is the only one. Honestly, though, I somehow doubt it will be seven who are being impatient, but just one or two who are vocally impatient and 5 others who couldn't care less and simply don't say anything--which leads the 2 to believe everyone is irritated.
