Why the Lego Batman Movie is for the fans

In February of 2017, the Lego Batman Movie, and this is why it will be a fan service, while also being able to pull in the Wayne bucks, the director movie said it is a "90 minute easter egg full of comic and movie references" this seems nothing more than fan service for all DC fans, since the Justice League will appear, which is something some fans, the ones who hated BVS, desperately need. It'll be kind of like Zootopia, full of references, but still be able to be a fun and entertaining film that will bring in the Wayne bucks.
