Shutter Island is one of my favorite movies to watch. Not just because it has Leo in it but since it causes you to constantly keep thinking and second guessing and doubting yourself into not knowing if everything was a lie or not. Also wondering if Teddy is real or if he is actually Andrew. The water and fire both had symbols. Teddy was scared of water it made him nauseous. When he talks about his wife dying in the fire and having dreams about her she never is burning only everything around them is burning .Every time Teddy gets a headache he takes the pills from the doctor to make his head better but ends up falling asleep and dreaming about Dolores and that is what is keeping him there initially. Then to counter his judgement for the most of the movie it is raining or somehow water is involved. Also the fact that if we the viewer are left to decide if Leo is really Andrew or Teddy. This makes us think about all the ptsd and stress trauma Teddy has gone through to really think about if he really who he claims to be. The fact that his partner was actually someone from the government trying to set him up on the island kinda sways the ideas again on which character is the real character.
