Parent/sibling who has good reason to hate their in-law

Obviously, the "in-law rivalry" is a trope as old as time. And sometimes the show wants us to think the in-law is unreasonable and too harsh. Other times, they kind of point out why they are right, even if the character themselves doesn't go about it in the right way.

1. Connie Tucker & George Cooper, Young Sheldon. Connie and George are kind of a lighthearted example of this. They snark, but they genuinely seem to care about one another. Still, it's mentioned a lot that Connie used to be really mean and hard on George. It seems unreasonable at first because, despite what The Big Bang Theory said, George was a decent husband who tried, and Mary wasn't always the best wife (which makes sense, as Young Sheldon is Sheldon looking back on his childhood in a nuanced light). That being said, when you realize that George was in his early 20s when he met teenage Mary and knocked her up when she was young...you can kind of understand why she wasn't always fond of him.

2. Vic Palmero & George Lopez, George Lopez. When we first meet Vic, you think he's an overprotective dad who would think no one is good enough for his little girl. And there are times when Vic goes way, way, way too far with George. He belittles him in front of his own kids and undermines him, constantly shoves the fact that George is less successful in his face, etc. But then again, you look at the backstory. Angie was a very smart girl who was on track to do great...when she met George, who really wasn't doing much with his life. Things went off the rails when they got married and had a baby young. Again, Vic shouldn't be such an asshole to George (especially as Angie made a choice, something she reminds her father of often), but you can see where he's coming from.

3. Linda Michaels & Bill Miller, Still Standing. Bill is your typical oafish sitcom husband with a hot wife who's out of his league, and he uses weaponized incompetence to avoid doing stuff. He often belittles his sister-in-law, Linda, for being single and childless, claiming she'll die alone. Linda also clearly does not like Bill. This is a case where the show doesn't want you to think Bill is in the right, though. They play his antics for laughs, but no one ever argues with Linda that she should be nicer to Bill. In fact, quite the opposite: oftentimes, people try to convince him to go easier on her.

4. Deb Scott & Haley James Scott, One Tree Hill. Deb is not the world's best mother, not even close. And again, some of the stuff she says and does is horribly wrong. But it's one of those situations where you get older, and you see where she's coming from. Haley and Nathan get married when they're only 17 years old (Nathan is emancipated, and Haley's parents sign off on it). She's understandably upset and seems genuinely worried about both of their futures. We also see that Deb lightens up in time and is nicer to Haley as the years go on.

5. Juanita Solis & Gabrielle Solis, Desperate Housewives. From the beginning, Juanita could tell that Gaby was no good and up to something. Turns out, she's not wrong. Gaby is cheating on Carlos. And yes, Carlos is an asshole in his own right, but Gaby only remains with him for the money (at least in the first season). Carlos suspected the affair and asked his mother to look into it. >!Juanita manages to catch Gaby in the act and takes a picture...only to be put into a coma due to a hit and run. She then wakes up from said coma and instantly tries to rush to tell her son what she discovered, and in true soap opera fashion, ends up falling down the stairs and dying before the truth can come out. (Though Carlos does find out anyway at a later point) Gaby later admits that she understands Juanita more once she becomes a mother herself. She'd do the same things to protect her kids. She even names one of their girls after Juanita out of guilt. !<
