Thor's Hammer

Building this is a study in patience more than technique. You start with the head, which is a dense core of 2x2 bricks and SNOT brackets that give the hammer its flat display faces, and that part is satisfying because you can feel the weight adding up in your hands. Then comes the handle, and this is where the repetition lives. It's long runs of Technic bricks joined with pins, built up over and over until the shaft reaches full height, so you settle into a rhythm and just keep going. The whole thing moves fast, five numbered stages plus a couple of loose bags of Technic bars and bigger molded parts, and you can finish it in a single relaxed sitting.

The parts value here is a mixed story, which is fair to say plainly. A lot of the 979 pieces are structural Technic bricks and bars doing the heavy lifting inside, so you're not pulling out a treasure chest of rare recolors. The real joy is in the extras. You get three neat little mini-builds, the Tesseract, the Infinity Gauntlet, and Odin's Fire from Ragnarok, plus a Thor minifigure to stand alongside. Best of all is the engineering trick in the head: pop the center tiles and the artifact plate clips onto two internal 2x2 brackets so the treasures hide right inside the hammer. It's a lovely touch, though fair warning, getting them back out means taking a good chunk of the head apart again.
