So it’s an incredible irony that Bay seems to have redeemed himself with Transformers, a film based on a line of toys of all things. Bay’s film not only delivers on its promise of a fun popcorn movie, it revels in its frivolity; this is the film that the abysmal Independence Day wanted so desperately to be, all those years ago.

As the Transformers mythology goes, two warring factions of giant alien robots — the benevolent Autobots and the evil Decepticons — left their homeworld of Cybertron for Earth, where their eternal battle continues. Here they take the forms of ordinary vehicles and devices: leading the Autobots is Optimus Prime, a heroic figure who transforms into a truck and gets to pontificate about freedom and the virtues of humanity, while heading the Decepticons is Megatron, who used to transform into a gun but in the film appears as a jet.

Any man who was a pre-teen in the mid-to-late ’80s probably knows all of this anyway. If nothing else, we all watched the animated series and have some vague expectations for the characterisation of each Transformer, particularly Prime and Megatron, but also fan favourites such as Bumblebee and Starscream. By and large, these characters are recreated fairly faithfully, but it’s true that the humans, not the Transformers, are the focus of the film.

Having the humans dominate proceedings would perhaps have been more problematic were the script not as fun or engaging as it is. There are moments of humour and whimsy sprinkled throughout the film that only occasionally fall flat — Bernie Mac in particular has a cameo that is absolutely hilarious (though potentially offensive to some). Full credit must be given, however, to Shia LaBeouf, who essentially carries Transformers during its slower scenes through sheer charisma alone. Also always nice to see is John Turturro in a supporting role, but the appearance of Jon Voight has to be the most surreal bit of casting since Orson Welles voiced Unicron in the animated Transformers film 21 years ago.

Of course, it’s the third act where the real robot-on-robot action occurs, and this is the payoff for all the exposition of the prior 90 minutes. A kinetic energy takes hold, and suddenly you’re watching two robots destroy the entire floor of an office building, for example, causing destruction and mayhem on such a scale that you can’t help but be awestruck. One can only assume that the sequel will be even bigger.

Sure, there’s a plot that’s buried beneath all this, involving metallic cubes, sexy love interests and pairs of glasses on eBay, but it’s just window-dressing to introduce the premise of this new franchise. Ordinarily, I’d feel insulted by this, but it’s done with such good humour that it’s hard to fault the film for not aspiring towards high art.

Maybe Steven Spielberg (as executive producer) is responsible for Transformers‘ sense of childlike giddiness; I don’t know. All I know is, it succeeds at being a fun and entertaining movie, and that’s all it should need to be.
