It's kind of hard to believe that it's been five full years since The Lego Movie was released (I've officially reached that age where I say things like "this years gone fast"), but really, quite a lot has happened in that time. We've had two The Lego Movie spin-offs, of varying quality. Star Wars came back. The Marvel Cinematic Universe went from big deal to maybe the biggest deal. The DC Extended Universe started in earnest, and then died on its ass, and then started again. Pokémon Go came and went, which for my money is still the last time the world felt positive. The USA elected their very own President Business. Bloody Brexit.
My point is that despite just how quickly the time has passed, a lot has happened in our world since the release of The Lego Movie - so maybe it's only appropriate that a lot has happened to the world of The Lego Movie in that time too. Picking up right where the first film ended before jumping forward in time five years, The Lego Movie 2: The Second Part sees the city of Bricksburg destroyed by Duplo alien invaders and rebuilt as a gritty, post-apocalyptic wasteland called Apocalypseburg, forcing the population (with Emmet as the only exception) to adopt a dark and tough persona in order to survive. But after an alien from the Systar system named General Mayhem kidnaps Batman, Unikitty, Benny, Metalbeard and Wyldstyle, it's up to Emmett to rescue them and prevent OurMomAgeddon, teaming up with a battle hardened space pilot named Rex Dangervest along the way.
