In Canada, the term assimilation is especially unpopular. It's associated with painful events in the country's history. But the country's proponents of forced assimilation often underestimated the inevitability of resistance on the part of their targets. The lessons of our history seem lost on many Canadians as it's surprising to learn how many endorse making "others" like "them." Paradoxically, several Canadians that continue to fear assimilation are amongst those most apt to believe that their own cultural survival depends others assimilating.
I haven't seen any surveys that say definitively how many five to twelve year old girls are frequenting comic book stores and watching Star Trek. I'm sure that the number, whatever it is, is higher than the numbers were in the 1970s but I'm willing to bet that it still disproportionately less than the number of boys.
Orphan Black is about clones and conspiracies. Part of the series' appeal is doubtless its gimmick. The twinning process -- wherein an actor plays opposite himself -- has been around for decades, but Orphan Black does it better than almost anything before. Even when the clones hand each other glasses you forget special effects are involved!
At heart, every story has probably been told, so it's in the details it's kept fresh. When Canadian filmmakers refuse to set their productions in Canada, they are basically announcing: "We have no intention of doing anything fresh with this material." If the creators aren't willing to fight for something as rudimentary as the setting, can we really expect them to fight for other things? Is the fact that so many of these filmmakers are unwilling to set their stories explicitly in Canada part of the reason why there are so few Canadian series and movies fronted by non-white actors? 'Cause that might be a fight with executives, too.
