Grimm movie

I just finished watching Grimm which makes me soooo sad BUT at same time it’s pretty cool that there’s a news article saying a Grimm movie is coming out!!! So excited but at same time wish it was a show instead of a movie cuz it would be a lot longer!!! I hope we get a lot of the same characters back but sense it was made sooo LONG ago ,I doubt it. Does anyone know what this movie is suppose to be about and who will be in it? Like is it gunna follow the kids instead of Nick? Or maybe trubel? Or go a totally different route? How long until it comes out? (I suppose that last question I can google to see when it’s suppose to come out). But yeah it’s def got me interested!
