I disagree because though MLP was initially aimed at young girls, in my opinion, they've already been trying way too hard to market toward girls focussing on things that aren't exactly relevant or even canon in the show such as characters who aren't even canon not to mention the poor quality designs! It's a fact that the Mane Six are girls but it seems that Hasbro focuses on the fact they are girls rather than their real personalities and cool stuff they've done. Everytime I check out the MLP toys in a store, I find myself cringing a lot at the fact they just keep trying something that's not exactly, in my opinion, true.
With Guardians of Harmony, I feel that this is a step in the right direction for Hasbro finally portraying MLP for what it is to most of us. With show accurate designed toys and better aesthetics, in this new toy line, we get to see the characters' awesome side to their personality. I would also like to point out that Guardians of Harmony is targeted towards boys AND girls which is a move I really like as the fandom is a mix of everybody. Also yes, it was called Lego Friends.
Bottomline, I see it the 'Guardians of Harmony' line as Hasbro finally bringing out the true gem of the show rather than market a side of the show that isn't really there and show that My Little Pony is something to be enjoyed by everybody.
