$20 for 229 pieces and a Rhino — the math was never going to math. This one skips right past 'budget set' and lands on 'why did I do that'.
The parts alone are worth about 62% of the street price — the basis for this F price read.
OverpricedYou're paying well above the parts' value — $22 of parts for a $35 price.
The Rhino minifig is the one thing holding this set together, and that's a lot of weight for a single molded head to carry. The mine setup is serviceable, barely — a few exploding bricks, some generic scaffolding, nothing that'll make a builder stop mid-bag and say 'oh that's clever.' Three minifigs sounds fine until you clock what you paid per figure in a $20 box and realize Spider-Man shows up in roughly fourteen other sets. As a display piece it's background noise at best. The C overall isn't a failure so much as a forgettable afternoon — built, shelved, quietly traded away.
