I guess I should've specified that I was referring specifically to the American version. There are apparently different versions of this show for certain countries, but they all mostly follow the same premise. There's already been one for UK and one for Australia, and I've heard plans are already underway for one in Germany.
As a Lego enthusiast, I'm definitely liking this show a lot already. Even after just one episode, I'm quite impressed by what some of these teams have been able to create (though other teams definitely have much to improve on). (I guess one thing I forgot to mention is that the competitors for this show consist of teams of two, with a total of ten teams at the start that are eliminated one at a time until the last one standing is the winner.) The challenge for the first episode was to build a section of a theme park, with a requirement of at least one moving component. I'd rather not give out spoilers, so I won't bother going into details on who did better than others and what exactly they all built.
