i'm just remembering something. there was a beautiful framing shot of marty at the dinner table and wendy in the kitchen in the final episode.
when the camera pans out, you see marty in the dark framed from the broken door symbolizing where he ended up. he's a broken man that lost everything to get to this point.
wendy, on the other hand, is in a kitchen with a florescent light symbolizing how she's business as usual in a cold, heartless game. she's shining in a place where marty is in the dark.
there were a few of these types of shots throughout the season that were foreshadowing, too. but i'd have to go back and rewatch. id always forget those shots cause something crazy happens in the episode
