True, it's just a feeling without any further info. So here's some info; the movie felt like it was only made because TFA has whipped up a new SW-frenzy and anything they release now under the SW flag will sell gangbusters as long as it's somehow related to any of the movies. You can get Vader and Death Star in the trailers, that will wake up even the moldiest of fans.
