Yep you definitely would think that as it was a great movie. Another movie that has the same kind of error though only a small one is the first Conjuring movie. I don’t think it has been discussed here but about half way to a third of the way into the movie there is a shot of the hallway in Ed and Lorraine Warren’s home. On the ceiling a very modern day disc looking smoke detector can be seen and this scene takes place in 1971 or so. Home smoke detectors did exist back then but they were a completely different shape. You would have think they would have caught that too. It was also a very good movie.
