All three of these are hideous. "New from Lego! Bobble Head Iron Man! Ugly Green Brick Hulk! And Capatain America, complete with Awkard Sheild (tm) and Stud Head (tm)!"
That said, the DC ones look nice. Thor and Wolverine look quite nice as well. But those three? Ew. Maybe put a helmet on Cap or something. Better yet, could just order one from BrickForge. Okay, that's one fixed! I stand by my opinion on Iron Man and Hulk, though. I guess the huge head is so they can squeeze in a Stark head underneath, but still...
That said, can't be worse than the Mega Bloks Marvel sets, right?
