As someone who hated the idea of a Lego expansion I gave it a try and so far I'm enjoying it BUT it feels like they've missed a huge opportunity with the Lego cars. They're barely modifiable. Why not let us do silly things like stick a pig on the roof or attach crazy parts to the car? That's the whole joy of Lego! Having only 3 new cars really sucks too.
I will say though that the world they've built looks fantastic and the bricks themselves have some incredible textures and surface response going on. The way they reflect the sunlight showing tiny scratches is superb. Massive kudos to the art team!
I may have also let out a pretty big laugh at the intro where the car revs up and then drives forwards towards the rectangular portal thing before just bouncing off the wall
