Well here is a few thing I noticed:
Lloyd dragon looks absolutely amazing!!
On the flashback scene there is the sushi chef minifigure on the front.
That thing that pushed down Lloyd from the Temple (?) what was that?! I thought it was Jay to save him from whatever but zooming in.. It is not.
Also it is weird that the movie is not yet rated but... that thing and that Lloyd is getting a "7 point arm-ripped-off" would make this movie to be taken in a more serious rate level than the previous Lego Movies.
