Honestly, in my opinion, the franchise doesn’t need a new entry.
Keep in mind, I love Chucky and the franchise, and despite the title, I will see anything they produce from the original timeline as long as I’m alive. But the truth is, we don’t really need a new entry. I think the ending to season 3 is as perfect of an ending as we will ever be able to get. Chuck is the main character of the franchise. And there is no death we could believe at this point is final. The series can only end with him “out there” causing havoc, being a legend. At the end of season 3, he’s won. Him and Tiff are going on a road trip with an evil child, GG is out exploring Europe. The three Chuckskiteers have been defeated. In my opinion, only Nika’s fate is unsatisfactory, but I’m willing to deal with that and just assume she’s a doll or dead. Again, I’ll watch whatever Don does with Chucky, but I think we got as perfect end to this timeline as we could.
