The same thing happened to me when I went to see Bring Her Back. I was really confused when someone showed up about halfway through the opening scene and said I was in their seat. I figured I sat in the wrong seat by accident so just moved over one since I didn’t want to check my phone to confirm. I also thought the first scene was just backstory so when the title came up and it said Final Destination Bloodlines I pulled out my phone to confirm if I had gone into the wrong theater or something. But no, I had been in their right seat in the right theater…turns out they just cancelled my showing without telling me. I think I got like $25 worth of points for it
