I agree with all but pinslave =-) I love my SMB. It is well themed but very simple playfield art. I think it is the color that turn most off. And never thought of doctor who as ugly just over the top and a little cheesy.
genesis, SF2, LW3, hard body, NMOES, raven... after that I am not sure there is much uglier out there. oh yeah barb wire I can deal with the BG not the PF.
Man for the era of these pins they did not spend any time or money on looks did they?
