For me, the newly-released Thor's Hammer set is everything that can go wrong with #LEGO :

• Brown and grey,
• Repetitive build,
• Design limited by a 3rd party license.

I don't need to have seen any Ninjago, Legends of Chima or even Monkey Kid media to enjoy the sets that came out of these themes. But who would be interested by this set without having read/watched Marvel's Thor in action?
