In fairness, yes there are two. So this is partially my own fault. I'm a 100% Scene card user which means I only go to Cineplex.
Actually, I just checked and in my defense the Landmark theatre there is no more (which isn't surprising, given Landmark went out of business in Canada, did it not?). The only other theatre is the old Paramount theatre, which is a specialty theatre which plays older movies.
So yep, it's just the Aberdeen Mall Cineplex for me. The theatre in Kelowna is even worse.
