What are The Good Place plot holes that bother you?

Let me preface this by saying I FORKING love this show, and the S1 finale was one of the most brilliant finales and unforeseen twists I've had the joy of witnessing. I definitely want to start another thread just to laud the brilliance of the many great one-liners on the show.

That said, I've been rewatching S1 to try to catch possible nuances I missed the first time around and a few things are bothering me:

• Why didn't anyone call out the fact that Trevor (Adam Scott's character) started the train back to the Bad Place with the "good" Eleanor still on there? From the perspective of an exchanging of gold and bad Eleanors that wouldn't have made any sense.
• Anyone else feel like we are missing a lot of Chidi's backstory? Being indecisive doesn't seem like enough for eternal damnation, and the indecisiveness didn't even seem blatant enough to show up til the end of the season, for the most part. In contrast, Tahani seems pretty arrogant from S1E1.
• The good things Mindy did don't seem nearly good enough to counterbalance the bad, not to mention based on what we know about Chidi, Tahani, or Jason, she doesn't seem any less good/bad than them. They haven't really sold me on why she'd be special enough to warrant her own special Medium Place with no one else in the same bucket.

What are your thoughts! Any other plot holes that bother you?
