The judges have proven themselves to be complete hypocrites time and again and I find it ridiculous that Dave Navarro with all his shitty little flash tattoos thinks he can criticize an artist. Other than that it's great
I think it's cool -- I watch it on my other screen while I do work sometimes.
But, I like tattoo art to begin with, and I also enjoy the personal dynamics of those shows (especially Shark Tank -- it's fun to see whether the contestants can "read" the different Sharks' personalities well enough to pitch the right way to the right ones)
Do you ask for a specific reason?
For the ones who don't finish in the 6-hour period, I sure as hell hope they eventually go back and complete the job! Lol
