LEGO’s New Lord of the Ring Set Doesn’t Hold a Candle to 2024’s Best Because of Sauron

The LEGO Sauron’s Helmet and Barad-dur sets, both designed for adult collectors, offer very different experiences within Tolkien’s world. The helmet is a striking display piece focused on iconic symbolism, while Barad-dur is a larger, more interactive build meant for extended enjoyment. When considering cost, space, and overall worth, these differences are significant. Ultimately, the presence of Sauron as a key element makes one set a stronger choice than the other.
