While they are far from the worst films in the world, the Transformersmovies did ruin Optimus Prime as a character, turning him into a ruthless warrior, and even Peter Cullen disliked his portrayal. There are a total of seven live-action Transformers movies, including five Michael Bay films and two sequel prequels, which span from 2007 to 2023. While the science fiction action films have generated an impressive $5.29 income at the worldwide box office over the years, being the 14th-highest-grossing film series of all time, there have been negative to mixed reviews by critics regarding the Transformers movies.
