Harley Quinn Cannonball Attack Reviews
Is this LEGO set a good investment?
“As a The LEGO Batman Movie set, 70921 Harley Quinn Cannonball Attack is a good investment and has been slightly outperforming a typical The LEGO Batman Movie set with an average annual growth hovering around 7%. While not the best year over year return for this theme, it still is not a bad investment for collectors.”

“This set is a fun addition to the theme, and offers a great starting point for modders. At it's regular retail price, it feels a little pricey. If you're able to find it with a 20-30% discount though, it's a pretty easy recommendation.”
“Batgirl is the same Batgirl as always, and is really nicely detailed. Cannonball Harley Quinn is a minifigure that did not appear in the movie, and was likely scrapped concept art. Gentleman Ghost is a pretty neat-looking character in my opinion. Crazy Quilt is a cool... More character to get.”
