The charm of this unlikely threesome has worn off.

This is the weakest season, so far. They are trying too hard. And it’s a bit painful to watch.

One tell is the increase in profanity. When the script isn’t all that compelling — writers add some swearing to shock the audience. Jon Stewart and John Oliver are guilty of this, as well.

BUT at least the cast is still having fun.

Martin Short and Steve Martin are best of friends in real life. I’m sure they consider this venture a bit of a party. Inviting their friends as celebrity cameos.

It IS worth watching season 3 for Meryl Streep.

AND there are some good 1-liners each episode.

Selena Gomez as snarky Mabel increasingly steals the show. You actually worry about her getting her life together. Yes, the same young woman who’s the most followed on Instagram looks lost at times as she approaches age-30 in this show.

It’s been renewed for season 4.

Something tells me that will be weaker yet. They probably should have retired after season 2.
