As for Kris, one thing to point out is that Kris DID take risks in this competition. Choosing Falling Slowly was a HUGE risk. Everyone else took on well known songs that they knew people loved. And Kris took on an indie song, that wasn't well known by voters.
Don't underestimate that this actually didn't gain for Kris a heck of a lot of respect because it showed that this guy has a pretty good knowledge of music outside of top 40. The guy essentially went "Indie" for that moment. And it showed that he has good taste in music. In fact, I feel quite strongly that for the most part Kris has better taste in music than Lambert.
