Kevin Spacey was brilliant in this. I loved it. When I heard about the plot line (an alien from a distant galaxy travels to Earth to observe things, but unfortunately ends up in a mental hospital) it sounded kind of hokey. But it's really anything but. Spacey made Prot one of the most lovable characters in mainstream movies that I've seen for a long time. Just like in American Beauty...he did an awesome job. And all of the other characters did a nice job, too...
