As Transformers 4: Age of Extinction opened this week, it has already nailed the mega-bucks at the box-office raking in a record-breaking $100 million in its first week.

Michael Bay Replacement For Transformers 5 Not An Issue

The movie has been the highest grossing in its first week for this year, thus far. So it seems like while fans are championing Michael Bay's fresh start with the franchise and this seems to defy the verdict of the experts. But the critics have been rather unkind to the film, with a lot of them outright disappointed with it and completely slamming it.

The reviews have been mixed for the movie so far, as some are fairly impressed by Bay's technical wizardry and others believe the sensory overload is ad nauseum.

Variety actually suggested that the plot bore "resemblance" to X-Men: Days of Future Past:

"The plot, as scripted by Ehren Kruger (who penned the last two Transformers movies) bears more than a passing resemblance to that of the recent X-Men: Days of Future Past. Just as the X-Men are hunted by Sentinels engineered by a paranoid government using mutant DNA, so the Autobots, after siding with humans in an apocalyptic clash against the evil Decepticons, are being targeted for elimination by a second generation of human-designed Transformers."

The publication also believes that Bay works a dangerous combination of an "aggressive sensory assault" with the "breakneck editing of William Goldenberg," which doesn't do the movie any favors.

The Hollywood Reporter took the most dramatic swipe at the movie:

"The age of the Transformers is over," announces counterintelligence agent Harold Attinger (Kelsey Grammer) in the fourth entry of the Paramount/Hasbro-backed fighting-robots film series. But don't you believe it: He's the villain of the piece, and, given Paramount's recent announcement that a fifth installment will ship in 2016, it's clear the mutating androids' reign, onscreen and at the box office, is far from finished."

This followed by the fatal blow, suggesting that this movie rings in the end of the Transformers franchise.

"Some viewers, though, will probably side with Attinger as they leave theaters after Transformers: Age of Extinction finallydraws to a close," the reviewer wrote.

But it's not all bad, Hitflix seemed to come out as a big supporter stating that this movie, which is in a sense a reboot for the franchise, has shifted gears in the right direction:

"Overall, I think this is a big step in the right direction. It's visually just as wild as the last few Bay films have been, with the director pushing ILM to their breaking point. It is amazing to me that Bay keeps finding a way to somehow make this these things even bigger than they already naturally are, but he is a man whose career can be seen as a series of escalating aesthetic decisions. He knows that these films exist largely to give fans a chance to watch giant robots beat holy hell out of each ether, and on that front, boy, does he deliver."

Transformers: Age of Extinction hit theaters on June 27, 2014.
