man everybody already got the good choices
elves, ninjago, bionicle g2, there's nothing left man
wait there is one more thing
I can't agree more on getting rid of Ninjago. There was something special about the first year of sets that will always resonate with me, and the next year will always hold the title of most disappointing move from LEGO in an original theme. Yes, even more disappointing that The LEGO Movie 2: The Second Part.
like my man likus I'm a sucker for good parts and I can't wait to get my hands on the sets to come from the movie, but my expectations for the movie itself are incredibly low
But that theme has already been picked (multiple times) so I'm gonna have to choose one nobody's touched yet... Creator.
I know - I just know - I'm gonna get hate for this, how not having new parts is the point, how I lack 100% creativity for hating on it, how I'm just another one of those people who builds everything our of Galidor because I can't afford to waste my money on any other theme lest it ruin my holy creations (I apologize if I'm the first person to actually say that) but I'm a kid who grew up with this theme back in the good old days, in the days where the biggest, bestest sets had eight different builds each with their own instructions and flavour, where dinosaurs a foot tall rampaged against mechs taller than any Bionicle set, over an imaginary world where three robots with shields and stupid ankles defended the countryside houses from being totaled by the giant ogre and the triceratops missing half its pieces, all the while the chewed-by-a-dog Panrahk moc lived peacefully and quietly with his set brethren, intermingling with other pieces in a peaceable manner not demanded solely because of the theme. LEGo sets and creations are never truly locked into a single scenario or concept due solely to the theme they come in, or the way the instructions tell you to put them together. And yes I know I'm a hypocrite who always says not to bank on nostalgia and I'm literally using nostalgia as one of my points, but... This theme had more freedom than ever to be whatever you wanted it to be, and now the bigger a set is, the less options you have, despite the part inventory at LEGO's disposal now being larger than ever before.
So yeah, cancel this Creator line. Bury it deep, and start over, because I know LEGO still has the potential to do what they did back then. They just aren't.
