I watched it on and off, but I tired of it pretty quickly. I think it was one of the first shows of its type, and they settled into a formula pretty quickly. Introduction to project, fab work, excursion (paintball, dune buggies, whatever), big fight, "we're gonna miss the deadline!", reveal.
I thought Jr and Sr had a big falling out and Jr started on his own? I'd be curious to see who that played out. The characters were interesting which is why it had the success it did.
I just realized that Pawn Stars has the same cast of characters, but with the addition of an old guy. huh.
