If you have Spike TV, it might be worth watching if your bored. Based on the Spike TV Video Game Awards, the production tends overdone and mostly groan worthy but it gave Harrison Ford the "Hero Award" for his body of work and did a 25th Anniversary thing for Star Trek: The Wrath of Khan so I plan on recording it for fast forwarding through the stupid bits (of which there will probably be many).
