I'm hesitant to post as I didn't have quite the same feeling the rest here did. I thought Murray phoned this one in - in some parts I thought he was outright bad. He seemed to have an accent for some parts of the movie. After the stroke, his debilitation seemed to come and go and change.
I also thought there was some predictability to the whole thing, too. I didn't expect Vincent to have a stroke and I did like the kids speech at the end that we got the title from.
