Rain Man (1988) - 6/10
This is a film about an autistic savant which was released long before autism, and Savant syndrome, were widely understood, so, of course, it blew the socks off everyone and cleaned up at the Oscars. Savants really do exist, managing all sorts of crazy genius; some can draw whole landscapes from memory, others can remember pi to the 2,000th decimal, and some just have a semi-automatic calculator for a brain. Dustin Hoffman does an excellent job of portraying one, arguably his best ever role.
