First, the lens is not handled properly. We all know that we saw a few minutes of footage. Actors may shoot for a few seconds from different angles, but they may shoot for hours for a minute we watch. That may be because their makeup is different from before, or they may change into a kung fu suit in a few seconds, and their bodies and looks are different. This person will be in many TV dramas. The man was injured and got an arrow in his left chest. Maybe the makeup artist's prop group forgot to put the arrow when making up the lens. Otherwise, when a person dies, his face is covered with blood, and the blood on his face will be gone in the next shot, which may be wiped by the deceased himself.
Second, something that shouldn't have appeared appeared. Most of them acted in costume dramas. An air conditioner suddenly appeared next to the old house, or an excavator. The protagonist appeared in the camera without taking off his watch, ring, cameraman and microphone. A group of ancient people obviously mingled with a modern person. These should be related to the later personnel. Some details control specifically look for these flaws from TV dramas.
Third, the lens is illogical. In fact, this aspect is also related to the above two aspects. The props were too careless when shooting. For example, a man said that he had been trapped here for three years and couldn't move, but in fact, if you look closely, you will find that the buttons of the bracelet tied to the prisoner are very loose and come out with a little movement. There are also soldiers with irregular gun postures in war movies, or the technical terms in medical subjects are wrong, and the wrong equipment is taken during the operation. These are all deceiving the audience. Or the makeup is inappropriate, too young or too old.
