I waited until Ep-3 to write this, hoping that the show would improve.
In my opinion ...
The Emmett character is the most awesome and authentic actor on the show, such a grounding force. Reminds a bit of Mel from Alice's Diner, rough on the outside, soft and cuddly on the inside. Emmett is always insightful, truthful, and wise - all without raising his voice.
Melissa Peterman needs to focus more on her comedy and her funny little phobias, and less on "I wanna be Reba's sister". We've seen Barbra Jean and we loved her, but Melissa is a top-notch comedian and she deserves better roles.
Bobbie is, as much as I love Reba, Bobbie is just more of the same as Reba Hart, she's such a Bully. It is always "do everything her way or take the highway". There is never a negotiation. It was the same way on her other show, granted on that show she kind of needed to be a bully to raise good kids and keep her ex-husband in-check. But it really is exhausting to have her yelling throughout the entire show.
The younger sister, Isabella, waltzes in and immediately starts pushing her millennial entitled b*s* onto everyone else. Not a funny character at all. This is supposed to be a comedy show, right? The age difference makes the entire premise of the main story line too far-fetched.
Takoda and Steve have so much promise. They need more screen time. If you cannot tone down Bobbie's yelling, then at least enhance and give us more of these two to offset the negative Reba.
Having worked in a bar, many of the background things that are going on are just disgusting ... wiping her face with the same towel that she just wiped Bar Glasses with; putting the white wine on the shelf instead of in the refrigerator; just the way they make drinks - it all needs to be more believable. At least on Cheers, it looked realistic, like they were really serving drinks - not just moving props around.
I will stick it out a few more episodes to see if they can develop these characters. But right now, even after three episodes, I still don't care about any of the characters - and that saddens me, I really wanted to love this show.
