I think they look great, and far better than their in-game counterparts. The Lurkers head looks a lot like Spike's, which I like, and I absolutely love the grey color scheme though it does seem off.
Were these already in the works back when everyone thought Gearbox would actually produce a quality product that could sell all of this merch or what? If they hadn't have screwed the game over, these could've sold well, not to mention the millions missed out on from the Wii port being cancelled.
