I've made it to the end of Episode 7 (out of 10) and I can't take another episode. This show is the worst. It's like an even lousier version of "Beaches" (Bette Midler, Barbara Hershey), which I consider one of the most maudlin, inferior movies I've ever seen.
Like Bette Midler's character in Beaches, Tully is insufferably self-centered and it's hard to believe she cares about Kate, her best friend, or frankly, anyone other than herself. There isn't a single likable character in the series (other than hot Max, who is involved with Tully, but I don't believe a solid, charming guy like Max would be attracted to or put up with a character like Tully in real life).
Don't waste your time on this dumpster fire. Life is too short.
