    I write this review more in the hopes someone at Lego sees this than anyone else. I think this set did not sell well because of the price and because if did not manage to satisfy boys or girls and fell in between. First off, the build is incredible. I love that the creative team created something so outside the box both in terms of design and build style. From the moment this set started with the castle part I loved it. The skeleton of the build is so fun to build. I really appreciate the creativity that it took to create this. I have nothing major to critique the build on. The figures are eh. All three are in a ton of sets and are not exciting. I wish there was more variations in prints or faces between sets. I wish lego could have included an exclusive figure that added some zest to it. As a grown man, I love the hairpiece for Mayhem. More of that though. I work with children and gender stereotypes are super fierce in children in the USA. It was not until I was an adult that I felt comfortable liking more feminine things. Even then I was initially embarrassed to buy friends sets until I got over caring. To boys this looks like a "girls" set, and to protect their masculinity they need to avoid it. I bet most are not strong enough, like I was, to bravely like much less want this set. For girls, the girls I play with are very picky when it comes to lego. We play with lego and very rarely do we build for long. Often it's strait to telling stories with the parts. I wish it wasn't like this; good luck finding a solution. The price is wild. In the US at least its about 20% over what it should be. I can get Mayhem adds to the price, but there are only 3 figures in a 50 dollar set so...and the two others had to be mass produced for multiple sets. This is one of only two sets I've managed to get on the third wave of clearance. Meaning that no one bought the 5 or 6 on the shelf when it was half off, or 60-70% off and it took it getting to 80% off for it to sell. Even then I doubt it was its target audience and more like guys like me that get it for parts. Again. I love the build. Hats off to the designer. But it was doomed from the moment the color choices were picked and the price established.

    Great pieces

    The original price was too high for me but I finally gave in when it was on sale. It was fun to build a different looking spaceship! All the play functions are great and I like how with the fold-out "feet" and moveable wings you can really pose the ship for display between play. The main reason I give this 5 stars/bricks is the pieces, lots of different and useable pieces like hinges and turning things and shapes for wings and more to create your own ships! So irresistible that after 2 days I took it apart to build my kids a Wild Kratts Tortuga that opens up, from a show they like. (They love it and I am happy left with the Sweet Mayhem minidoll, that has a different face than the one I had previously!)
