What age for kids to go cinema alone?

[NotmySundaybest]

DS is 12 and wants to watch the new Kong film with mates. Would you let them go alone?

Yes, secondary school children should be sensible enough to go together without an adult.

hell yes!

Yes let me daughter go year 6 age so 11, was dropped and picked up from the cinema.

Of course 12 is OK.
