These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Is Reba a wise, caring mother and grandmother, looking out for her kids and suffering her friendship with B.J.? Or is she a bitter and meddlesome control freak? (As with most things, the truth is most likely somewhere in the middle.) Several episodes throughout the show addressed this, with people telling Reba she had to let go and let her kids make their own decisions.
Anvilicious: The season 5 episode "Parenting With Puppets" is little more than a half-hour anvil drop about discipline in parenting.
Ensemble Darkhorse: Barbara Jean, especially in the later seasons. There were a few early episodes she didn't appear in, but popularity elevated her to a regular character instead of recurring.
Les Yay: Barbara Jean can come off as this towards Reba. Especially in later seasons, as Brock and Barbara Jean's marriage imploded; at that point she truly did like Reba better than Brock.
Rescued from the Scrappy Heap: You'd expect Barbara Jean to be the most hated character of the entire show, but she puts so much effort into trying to be Reba's friend that many, surprisingly, find it hard to do.
It helps that she genuinely feels bad abut wrecking Reba's marriage.
Melissa Peterman's complete devotion to a character that's absolutely loopy helps too.
The Woobie: Kyra, of all people, surprisingly qualifies as this, due at least partially to suffering from the Middle Child Syndrome. It also helps that her actress is a bit of a real life one herself, especially in Season 5, due to her anorexia battle.
