Boo

"With a BrickScore of 73.5, the Boo / Series 3 Character Packs deliver charming, all-brick Mario characters with clever interactive mechanics — but the blind-bag experience is badly undermined by a duplicate rate that multiple buyers found infuriating, making this a set best admired for its design while approached with caution at the checkout."

The LEGO Super Mario Character Packs Series 3 (71394 – Boo) earns a BrickScore of 73.5, reflecting genuine enthusiasm for the character designs and interactive functionality tempered by a recurring, frustrating complaint: poor randomization in the blind-bag distribution. Expert reviewers praise the all-brick construction, themed display bases, and fun in-game interactions, while owner reviews are sharply divided between delight at the characters and anger at pulling five or six duplicates from a single box. The designs themselves — especially Shy Boo, Scuttlebug, and Torpedo Ted — are broadly celebrated, but some repetition from earlier series and a few inaccurate color choices draw mild criticism.

Where they split: Expert/enthusiast reviewers (BricksFanz, Brickset) were broadly positive, focusing on design quality and play value. Owner reviews on LEGO.com split sharply: some buyers were thrilled with variety and character depth, while several gave 1-star ratings driven entirely by duplicate frustration — buying 6–8 packs and receiving as few as 2–3 unique characters. The characters themselves drew little disagreement; the blind-bag distribution mechanic drew a lot.
