It's possible...
1. Find an isolated cinema... But most probably it's not gonna be
comfortable... You won't be able to do more than a few mins from
there....
2. Find a showtime where there're less people... There're such
thing such DIRECTOR's seat... Let your gf sits on your lap.... But
have to be very quiet.... And the other director's seat cannot be
occupied... Unless you want other eyes watching ya...?
