Here is my very opinion filled piece, it is not intended to trigger or attack anyone. Please understand my experiences with the brand may not be the same as yours, and we may not share the same tastes. Narratively, it is a shame if we never get a conclusion to the Unicron storyline set up in The Last Knight. One could hope that now that the films are on the way out, maybe IDW could be permitted to pen their own vision of the conclusion of that story arc. Cinema as a whole is a very struggling format, akin to video games, where budget keep going up and thus studios feel obligated to hit numbers in the billions; or else people will decry your film a flop, even when it's still very profitable like The Last Knight. Due to the size of the typical Transformers film cast, it has been a real struggle to get meaningful characterization; often the best characterization being created by fans interpretation like Vangelus' "Murder Prime". I'm honestly not sure that feature film is a good media for Transformers. So far we've mostly had films that can be summarized as mastubatory spectacles of visual effect set pieces. That said, I do appreciate the benefits that were reaped from the successes of these films. I appreciate the attempts of a different visual aesthetic than what had been come to be expected. Was it always a success? No, I don't personally think so and I have found it difficult to be personally invested in any of the characters; especially due to them being treated at times as simply a prop to eventually rag doll, or unnaturally fall to pieces. By no means have I hated these films, with the caveat that Revenge of the Fallen did significantly catch my ire. I don't really feel like the films had much of a narrative vision, and had very inconsistent myth/worldbuilding. Did some neat visuals, and concepts get produced along the way? Sure, I won't lie and say these films had absolutely no value; they certainly did to the studio, or we wouldn't have gotten 5, and the upcoming Bumblebee film. However, this franchise is built on change and I think it's probably overdue for one. The film series likely could have comfortably ended with Dark of the Moon, as in a lot of ways Age of Extinction attempted to be a soft reboot. Could the 6th movie potentially have ended the new trilogy on a high note? I think it's a possibility, but unlikely. We would have gotten more of the same, more than likely; and if that's what you wanted, then I guess that's a shame you'll likely have to just settle for the Bumblebee solo film. I'm not gonna celebrate this chapter heading to a close, nor will I belittle those that found great personal pleasure from it. All I can say is, I hope that whatever new vision comes our way learns from what did or did not work from the past. Perhaps a simpler, smaller scale, and more intimate cast film set in the Cybertronians Civil War might find some real success in character based storytelling.
