Ultimate Doom had a robe thing, the mask wasn't reminiscent of a Dark Elf's, and the goat legs was the one element exclusive to that variant. About the only thing it got right was the full metal body, which isn't exclusive to the Ultimate variant (or for that matter, any armored character).
It's not unreasonable to expect something beyond the superficial to at least qualify for the adjective "clear", though.
Just look at Drz's "Pantheon of Doom" pictures. There's a recurring design template that's not present in the leaked design.
Except FF won't have the Midas touch of Michael Bay, recognizable stars, the dumb humor and spectacle that these audiences like to eat up, and strong brands like that of the Transformers and Turtles. Plus they weren't dumb enough to schedule their movie against multiple movies that can steal their money-making demos (Turtles only had GOTG to contend with, and that was on the previous week).
It is interesting that some proponents of this film are already bringing up the Transformers/Turtles comparisons, as if despite their positivity they're already resigned to this film sucking and are just banking on the "even bad films make lots of money" phenomenon to salvage things.
