I’ve decided to regard the second half of season four and all of S5-6 as a sort of Grimm-Writers Fanfiction and enjoy the Grimm I loved :-D cause I just can’t stomach some of the crap that happened in the later seasons

Yeah…I think the fandom is basically split down the middle in this regard. Either they loved the last two seasons or hated them.

For me personally, I feel like the show was still good up to about 2/3 of the way through season 4. And to be fair, it was still good after that, too, in some respects. It still had some great moments with all of the characters I loved, good dialogue, fantastic acting. Several episodes in season 6 were at least as good as season 1, and the whole season had the same feeling the show had in season 1 as well.

But it also had its bad points, things the writers wanted to happen but didn’t put in the time to make work within the story and characters they’d already built. And the big payoff to the whole mytharc that started in the very first episode feels rushed, cobbled together, and a little underwhelming, in retrospect. Then again, I’m not sure there’s anything they could have given us after 5 seasons of buildup that would have felt completely satisfying.

So I feel you, I really do. As much as I love some parts of the show, I’m only able to accept others because of all the headcanon room the writers left us in the final episode. Which at least says something about the writers themselves…that they knew their audience well enough to know that they would never be able to please everybody, and cared enough to give as many of us as possible something to walk away happy with at the end.
