Well, it's public domain. Just like a person can remake Romeo and Juliet about singing animal-themed gangs on the mean streets of the city, people can remake the Green Turtle or any other superhero they like in whatever image they please.
And if it's not good...? Well, I haven't liked much of what the mainstream industry has produced in pretending to respect the characters they revive, so it's not like one more misstep is going to bother me, at least.
