I really don't like that excuse. Just because it's been seen in print, it's "from the comics" and therefore, somehow valid. When the TASM costume was revealed, there was uproar about how it deviated so much from the classic design- Then someone posted a page from a one-shot, revised origin tale from years ago that no one even remembers showing a costume that kind of, a little bit bore a couple similarities. They seemed to be happy with this because they could tell themselves it that the TASM suit was "from the comics".
My qualm with that is that there's no history there, these "new" looks aren't iconic and memorable in the way the "classic" costumes are.
But you know what? If they really blow me away with a really stellar, well put together film, I won't be too bothered about Electro's look.
