I may be a little behind, having only seen this film recently, but the first thing that popped into my head after "holy shit that was brilliant", was "how do I wargame this?" I know of (and have trouble resisting) Brikwars, but I was really struck of just how much the climatic battle of The Lego Movie was reminiscent of something like The Avengers or Justice League: New Frontier, with everyone banding together to fight the villain. Also, if you squint at it a little, the protagonists are a little like a super team.
So who are the heroes of this interlocking-adventure? The leading plastic man is Emmet, a construction worker, not a lot of playability there until he becomes a "Master Builder" in the third act. In fact, all of the heroes are Master Builders, a cabal of expert Lego-kitbashers who can turn anything into anything else. The only foreseeable obstacle to gaming this hero group is that they all share the building ability, making the entire team Gadgeteers. That thought aside though, the team also includes a Wizard, a magical cat creature, and astronaut, a cyborg pirate and... Batman.
As family cinema The Lego Movie gets a 9.5 (assuming Who Framed Roger Rabbit as a baseline for 10 in the genre). As inspiration for Superhero gaming, it's worth a look, I'm already scavenging parts for a 28mm Metalbeard.
