It is good imo. But I don’t know what you mean about problematic parts because the show itself is about a problematic character. All the bad things you see are never shown as “good” or romanticized (I’d find these things “problematic” if they were shown as something good in the narrative or if the Jean/Sidney ship was shown in a romanticized light but it’s not). Jean is an antihero, she is extremely flawed but so are all the other characters, every single one (except Jean’s daughter, she’s adorable). The show is about people that are grey, they are complicated. No character, relationship, or situation is 100% good or bad. 

I think it is, I loved it. But it’s definitely not a fluffy show. 

The main character, Jean, is a complex and highly flawed woman, she’s an anti-hero. She starts off the show just wanting to help but by the end things get out of hand for her so you’ll see her do things a “good” lead wouldn’t do. The supporting cast is also full of imperfect characters but they are all likable in their own flawed ways. 

If you want a show with pure happiness this is not it. If you enjoy a show with complex characters who’s motives aren’t always crystal clear then this is it.

If you want a show where the main “romance” is the epitome of health, trust, and romance this is NOT it. But if you enjoy complicated relationships that aren’t always healthy (and most importantly aren’t romanticized by tptb) you’ll like this. *I’m not saying there isn’t any romance between the main couple, they do care about each other (in their own way).
