It seemed mostly to be close-ups of the faces of Joan and the priests talking. Presumably this was meant to draw the viewer into the film, and engage them emotionally. The problem is that a film consisting mostly of conversations is ill-suited to the medium of silent cinema. Intertitles were used sparingly in this film, which meant that most of the dialogue which was obviously happening wasn’t relayed to the viewer.
I think my main problem with the film was that I never managed to make an emotional connection to the film. The subject matter was in theory interesting to me, but I just couldn’t engage. Part of the problem may be the assumption on the part of the film that the viewer is Catholic; there are a lot of scenes of Joan choosing between her belief that she is called by God, and rituals of her faith, such as going to Mass. On the other hand, it could just be the monotony of the visuals that meant I was falling asleep towards the end.
My views are perhaps best summarised by how long I spent trying to work out what language the intertitles were in.
