Knew it, when I first saw the report I was honestly surprised, I like firefly as much as the next nerd but a lego form? It's no way near as ambiguously-tame-horror filled as say, something like Star wars. The Reavers are genuinely terrifying and described and portrayed as such.
As well as the main cast although awesome, not...exactly a shining pinnacle of what society deems, moral human integrity.
I would have loved for this to come out personally, but I can't see it being appealing enough for kids to justify.
@Marc Pearce, Batman has over 30 different incarnations, when creating the lego form they used the template from the Cartoons/Lego games, more a slapstick, detective, goofy fighting tone. Firefly does not, it has one incarnation, and it's very gritty.
