The story didn’t match up with how bumblebee and the others got to earth in the first place.We learned that Bumblebee helped in WW2 in the 5th movie by micheal bay, but in this movie, it shows him just coming to Earth in the 1980’s. And in the first Transformers movie, Ratchet states “his vocal processor was damaged in battle (cybetron war)” but in Bumblebee, his voice processor was destroyed by a decepticon on Earth. There’s a lot of ends that didn’t connect with the actual series “Transformers”, and I have more facts too.
