"The BrickScore of 67.4 captures the expert take: competent but not exceptional as a Technic model, with licensed proportions that are approximate rather than precise. However, 10,257 owner ratings averaging 4.8 and a 94% would-recommend rate make clear that as a play set for Monster Jam fans, it significantly over-delivers on expectations."
The 2021 Technic Monster Jam Grave Digger earned a BrickScore of 67.4, landing it in Mixed Reviews territory among expert aggregates, but owner reception is remarkably strong. With 10,257 owner ratings averaging 4.8 out of 5 (4.8 on Amazon alone), and 94% of LEGO.com buyers recommending it, this set is one of the most universally loved by actual buyers in its tier. The expert score reflects a moderate assessment of design fidelity and Technic depth rather than a dismissal of the set's play value, which owners clearly find excellent.
Where they split: The most notable divergence is between the expert BrickScore of 67.4 (Mixed Reviews) and the overwhelming owner enthusiasm at 4.8 average across 10,257 ratings. Critics weighted design accuracy and Technic depth, while owners prioritized play fun, durability, and the Monster Jam license. Both assessments are valid on their own terms.

"I really wish that this had more functions, though, just something else. A little bit of suspension action, the ability to to to dial in some steering so it would actually go in in a circle rather than just always going straight."
Owners praise the Grave Digger's durability, pull-back motor, and fun building experience, though some note the model lacks visual detail, realistic suspension, and occasional quality control issues.
