I just had a movie idea where Octo ends up in a world where Ghostbusters never existed and, after he gets over the shock, fights to create Ghostbusters in a world without Bustin'.
Of course the ending is bittersweet because, while he is lauded as a hero, Octo also cannot bring the friends and romantic interest back with him to his world.
I wake up in this world and announce “Nothin’ makes me feel good”
