The Exorcist might be a show that many wrote off as soon as they heard the name, but this is without question the surprise of the season, and almost bizarrely fun.
The Family goes through the motions of many shows that came before it in the now popular long-arc realm, but it doesn't seem to understand what worked, beyond making things dramatic, and hoping for secrets.
One Big Happy needs you to settle in with it. It's working a theory that you'll like these people, as opposed to having to make you laugh ten times a minute. It has the cast to pull it off, and if you're on board for something that is insanely fun, instead of funny, you'll be glad you gave it a shot.
