I like it? It certainly has episodes where some of the challenges feel more sane than others, but I generally think it's a good example of skilled people getting to use those skills in creative ways, with a minimum of manufactured drama or bullshit.

(Honestly, for all the stunts they set up, the biggest challenge aside from the time limits seems to be the smiths against themselves, and that rings pretty true to me.)

Anywho, there's a small metric fucktonne of episodes out there, so I'd suggest picking a few and giving it a whirl. :)
