What was shown in this episode (“Patty”) may be a good place, but I don’t believe it is The Good Place. In fact, it may be a more insidious version of The Bad Place (not the original Bad Place with butt spiders and penis flatteners, but maybe Shawn and Vicky’s version of Michael’s version of the Bad Place).
I don’t know what The Good Place will turn out to be - probably not a place at all, but an opportunity to do good, be happier, etc., whether via reincarnation or being transformed some other way - some manifestation which is both you and not you.
I hope that Eleanor, Chidi, Jason, and Tahani are the first ones through the exit door and go because they have faith about what’s on the other side. I’d hate to see anyone go through it just toescape the boredom.
