Well, I can’t tell you for certain what the anon meant when they asked that question, but I can give you a short list of the things about this season I haven’t liked at all, which have worked together to contribute to the problem:

• the forced development of a romance that makes no sense between Nick and Adalind.
• the “hexenbiests and zauberbiests can’t help being bad” thing that is the only explanation they’ve given so far for why Team Grimm (and the audience) should forgive Adalind or why Sean is acting so OOC.
• Sean being completely out of character, while we’re at it, and the show giving no decent explanation for the sudden change.
• years of character development for Sean and relationship development between him and the rest of Team Grimm thrown out the window.
• everyone blaming Juliette for what happened to her while never taking responsibility for their part in it (except Rosalee, god bless Rosalee).
• Adalind getting tons of understanding, support, and the benefit of the doubt from Team Grimm while having done nothing to earn any of it (and in fact having a history that suggests she shouldn’t be given any of those things).
• Adalind’s entire character and her arc being scrapped with a retcon that waters her down and robs her of nearly all agency (not to mention makes no sense in the context of the rest of the show).
• the show abandoning several important themes that have always been at the heart of it (the power of choice over nature, for example).
• Bud Wurstner being nowhere to be found.
• the lack of trust between the members of Team Grimm (because I absolutely consider Sean a member of Team Grimm); the split and messed up and uncertain loyalties between people who were toasting to their friendship after risking everything to save one of their own barely more than a year ago.
• the general “sea change without satisfactory explanation” that has been enacted on so many characters, relationships, and world dynamics.
• the show’s continued inability/unwillingness to acknowledge that men can be victims of rape.

Just to name a few. I’m still hoping the Grimm Writers will pull through in the eleventh hour, but even if they do, some of this will seem just completely unnecessary.

And the really sad thing is, I think they’re doing most of this to try and make the show seem darker. Yet overall, the show is not really any darker than it’s ever been. Just murkier. Nothing makes sense, and not necessarily in a way that feels intentional.
