The result is not like a think it will be. Many people think that faces from debut to 1990, and from 1990 to 1996 are the best. This is what I think too, but I didn't expect that only smiley face are equal in preference has second period.
The result for the 1996 to today is not suprising. Most people think that they are something OK, but sometimes ugly.
The smile of the minifig makes the difference...
They seem to be happy, and suggest us to be happy too !
