I enjoyed this movie a fair bit, though I think I'm more in love with the idea/concept of Harvey than with the actual movie. Stewart is a delight to watch, as ever, in one of his best performances. I must say the screenplay feels a bit muddled, and the main character (Harvey!) feels underdeveloped. That last part sounds like a joke, but it isn't. Harvey never becomes more than a rather shallow figment of one's imagination. And that's a shame, because Stewart sure makes me curious about him.
