Jake Gyllenhaal gives a nice performance as the gentle, innocent Jimmy. But the film is full of political incorrectness, making sure it insults as many people as possible, from side show “freaks” to people of faith. Few groups go unscathed. But perhaps its greatest offense is that it really isn’t very funny. Once Jimmy is on the road, the major humor stems from the bubble wrapped young man being bumped into the air by fast moving vehicles. The rest of the gags are either insensitive, tasteless or in need of a rewrite.
