I think that the whole experience was mostly negative for Charly for many reasons. I think that the experience was negative because Charly wanted to become smart and that is what he got but he wanted to stay that way and that is what he thought was going to happen. The doctors never told Charly that it all was just going to be temporary. I thought it was a negative experience because it was like getting something you love for christmas, but then having someone take it all away. That is what I see happened to Charly and I think it's a negative experience.
