I agree with Lind Whisperer, I feel as though the comedy the show uses is absolutely of the belittling variety. It's not 100% mean-spirited, but nearly every character who likes "geek" stuff (which is to say, primetime television's idea of geek stuff) is depicted as an introvert. It'd be one thing if there was a foil, a well-adjusted "normal" person still into "geek" stuff, but the show's message more often than not comes across as "if you like geek stuff, you're a weirdo." There's exceptions, as I believe every one of the main characters now has a girlfriend for instance, but that's more just the show's progression. I also believe, despite this statement, more credit is being given than is due. In reality, the show is simply a one-track joke of "get it, they're nerds!" And the implications seem more like unintentional side effects of this method. Still, the fact that the show by-and-large treats their "geek" hobbies as a negative thing frowned upon or mocked by "normal" people makes the idea of Big Bang Theory Lego sets ironic. The target audience of TBBT is the same audience that would more likely than not be... persuaded to mock the Lego collecting audience by the show, in my opinion.
