Portrays Walton as complete idiot
First, he is shown recklessly riding his motorcycle through town like a teenage punk, nearly causing traffic accidents and hitting pedestrians on the sidewalk.
Then, he leaves the truck and casually ambles toward an unknown and ominous craft like an utter fool - while five other guys are frantically screaming at him to stop acting like an utter fool. Finally, he gawks at the purty lights like a knuckle-dragging moron seeing his first rainbow - until he is zapped to hell.
I don't know if Walton admits to this behavior, but the movie didn't pain him as having an abundance of brain waves.
