I watched it and liked it as well.  I especially noted that no one asked
what his disability was until about half way through the movie.  I think
that was the only time he said he was CP.  So it wasn't a story about having
CP, but about a very "patient and persistent" man who was very good at what
he did.  The only unrealistic part that kinda made me chuckle was how
quickly and easily he took steps up and down!  I can't speak for everyone,
but I know I have never been able to navigate steps without railings
successfully and even with a railing would never bound up and down them the
way he did!
