They aren't the same characters due to a technicality. But they are most likely playing the same personality, just with boobs, and make-up.
Which is a terrible move IYAM.
I am planning on giving this movie an honest chance, I adore Ghostbusters. But giving the new characters the same personalities just makes it so much easier to compare it to the original movies and thus harder for OG fans to give this movie a fair shake.
Then again, this will make boatloads of money regardless, so why should the studio even give a flying fuck.
I know for a fact from the script leak this is not the case at all. No need to make up bullshit.
WELL THEN. Back on board.
