Brainstorm has a killer concept for its time about a headset designed to allow others to experience the physical pleasures of another individual wearing a pairing headset. It's well cast too, and Louise Fletcher's performance is easily the stand out. It's just too bad the film's interesting setup just kind of died and went nowhere. For such an thrilling concept, not to mention the film's genius of making the regular scenes in 1:85:1 and the headset sequences 2:35:1, the rest of the film is rather slow and doesn't build up enough to make us care. It's a very indecisive film, and it's just a bit off balance. I understood a lot of what the film was going for, but it missed its mark. The movie was fun, sort of dramatic at the beginning, than turned into pain and conspiracy, than became psychological. It was too disjointed and all over. It's too bad, because there's a lot of great scenes in this movie with the characters developing and experimenting with the invention, the headset becoming an object of trauma and psychological damage, and the thrills emerge fairly well. Its pace just kills it in the end, and while the concluding act brings the film back up to speed with some action moments, it then becomes a bit rushed. I can assume Natalie Wood's demise may have ultimately affected some of the shooting and the final film, given how the production had to make its way around her death and ran into issues. A missed potential for sure, I'd watch it again for some key scenes, but otherwise it's a unfortunate disappointment.
