True… but… originally, Transformers was just a 3 part mini-series which had such success, they followed up those 3 parts to complete a 1st season which lead into 3 more and then movies and more cartoons etc…
What they did with the new movie pretty much was combine the 3 part mini series into a movie and tech… this movie ends off where the 3 part mini series did, the autobots won and the decepitcons are at the bottom of the ocean. Only difference is they changed the story line slightly, like how and why the transformers come to earth in the 1st place.
