Age of Extinction wipes out the competition. Transformers: Age of Extinction rolled out to an impressive $100 million opening in the U.S. and $301.3 million worldwide, becoming the top opening film of 2014. Its opening is not the highest of the series: that still belongs to Revenge of the Fallen ($108 million). Although the film cost an estimated $210 million, the film has already made most of that back, even if you add marketing to that total. The success of its opening week can be traced to two things: Director Michael Bay reloading the cast with the more fan/press-friendly Mark Wahlberg and better heavyweights Stanley Tucci and Kelsey Grammer, and the Transformers name itself, which always guarantees large opening crowds and plenty of buzz. And while the film has gotten slammed on RottenTomatoes - with a measely 17% approval rate - it's faired better on other sites like CinemaScore, which was given an "A-" by fans. We weren't impressed at all with A
