There should be a seat number on the ticket. This happend for rouge one when got released for first 10 days. So you cant sit anywhere..........
Back in the day, if you bought a movie ticket you would have to go to the theater early to find a good seat. Nowadays, theaters have assigned seating which means that seats are chosen ahead of time, so when you get to the theater, you already know where you are sitting.
