I think the "Russel Effect" is really people sitting at home and laughing as one seemingly "smart" person goes through the game and up-ends it because of the stupidity of most of the other contestants. It was surprisingly refreshing to see someone, good or bad, at least seriously gameplan and completely outwit others.
The show is supposed to be Outlast-Outwit-Outplay and until Russell it had been several seasons since someone really played the "outwit" card. Lots of people outplayed others, hangers on lasted until the end, but the smart game was really lacking.
I'm in for the season, it's fun, but there are about 4 people who need to go home. Like right away. Which makes this less fun when you feel as though you know a large group of people who have no shot to make it to the end.
