Just watched it. As someone who was in highschool when Donkey Kong got popular(I can remember going to Chuck E Cheese to play it when I was a freshman in HS), this was both nostalgic, and hilarious.
Billy Mitchell is classic, you couldn't write a character that perfect so for that to be the REAL guy is amazing. the hair, the wife, the refusal to play Steve while constantly saying head to head is the true measure of a player.
My girlfriend didn't like it much said just a bunch of nerds competing to see who was the biggest nerd.
Definitely liked it as a kid going to the local arcade there was always some kid there who was like Billy, but you just never imagined 25 years later those kids would be grown ups and yet still be the same obsessed players of those games.
and I loved the referee guy, that it was so important to him that scores be legit that he invented the entire format for checking them.
Highly recommend the movie.
