Pros & cons
What I actually noticed.
LEGO Ideas Dinosaur Fossils
Pros
- Three complete dinosaur skeletons (T. rex, Triceratops, Pteranodon)
- Each on its own wood-look display base — modular and rearrangeable
- Retired since 2021 — secondary market up 60%+ over MSRP
- Skeleton anatomy is surprisingly accurate for a LEGO set
- Best value retired LEGO Ideas set per piece
Cons
- Skeletons are static — no articulation or movable poses
- Aftermarket pricing has crossed into 'wait for a deal' territory
- Display bases are unforgiving if you bump them — skeletons separate easily
LEGO Ideas Home Alone
Pros
- Five rooms, fully furnished, every key movie scene captured
- The 'booby trap' details — paint cans on the stairs, BB gun, hot doorknob, tarantula
- Marv hanging upside down from the basement stairs — most-photographed LEGO scene of 2022
- Retired since 2023 — secondary market up 50%+ over MSRP
- Front of the house opens like a dollhouse for full interior access
Cons
- Aftermarket pricing has crossed into 'is this really worth $450' territory
- Some of the smaller booby-trap details are fragile and easy to misplace
- Christmas-themed build is harder to display year-round
