I avoided Brickheadz thinking they were just too expensive, $13 CAN.
My local Walmart had the Marvel Superheroes Brickheadz on for 50% off so I picked up 4, Captain, Ironman, Hulk, and Widow. I put them together in that order which worked out well since Widow is the more complex. Other than the a few printed pieces, I wasn't really impressed. A coworker kidnapped Hulk but I really don't miss him.
My local Dollar store got in a shipment of the last batch of Kubros for $4 CAN each. I picked up Spock and Terminator. The piece count is almost double the Brickheadz. The build is far more complex and I could tell someone put some thought and effort into the design. They're pose able. They're bigger/taller and more impressive on display next to the Brickheadz. I went back and bought the rest of the set.
I was thinking that Lego did a poor job on the Brickheadz.
Then I see the Bobba Fett and Carbonite to be released at NY Comicon. I do think they look cool. I'm not planning on spending the small fortune on these.
I'll be watching to see what Kubros comes up with next.
