I can contest to the movie being awesome.
I remember playing with Lego a lot growing up, and the film really captured what a whole Lego Universe would be as if staring at it through the eyes of a child. And without spoiling too much, the plot twist and subsequent scenes almost made me tear up since they really hit close to home and really spoke out what I felt like Lego should be.
If you're a Lego fan...go see it!
If you're not a Lego fan, don't let that deter you because it is just AWESOME. Seriously, it really is.
