You know, it's weird. I can see a million different areas in products and media where this a bit less attractive to downright awful, but I always love keshi in cross promotions with products, and the stranger the better.
Maybe I enjoy the idea of tiny, rubber, minifigures getting in the hands of new people, but I think it has more nostalgia than that. I think my acceptance of promotional keshi dates back to the cereal box toys of the 80's and 90's, especially the rubber Flintstones figures we all got. I would argue that keshi has always tried to be that freebie attached to some product, so that's why it may get the pass while others don't.
I particularly love the plain red ones, and plan to be getting a good little lot sometime soon on the second market. Now, the red bases the figures stand on are a giant eyesore, but it's no where as bad as the Marvel Test Tube Goo bases are. I'll certainly do a more detailed review once I get a few in my hands.
