I've spent a long time going over this guy. I've ridiculed, criticized and complained about Mattel's work with the Retro-Action DC Heroes. Finally I have my review up of Lex Luthor. I did this review from a Mego collector standpoint. So if you're not even the slightest bit interested in Megos, knock off two full points from the final score. So how did he shake out? Check out the full review, which I believe is probably the most thorough review of this figure on the net today.
