Alex had a LOT of input into the 13" figure line and was a big proponent of them them being that new, larger scale.
Then he was just as misguided as the rest of them. Pardon me for assigning their usual marketing naivete to just them. A super, revamped 12" body would have been great. What they did was not. The Lex will tank and we will not get anything like seven main JLA figures.
I love his art as much as anyone. And I buy into the "iconic jack kirby philosophy" stuff that he spews a bit as well. But making real life versions of superheroes that wear shiny disco spandex can only fo so far before it becomes offensive.
I can repaint a plastic Aquaman's horrible factory painted satin green pearl legs and add the black trunks if I want. Or repaint Flash with a non-cheesy Ben Cooper halloween suit. Lots of people can. But there's very little most of us would be willing to do to change an $80 (or even $40) figure that has gymnast performance satin blues and greens in a sewn outfit.
