Although Bumblebee seemed to be something of a refreshing experience for many, the franchise that was once so explosively awesome and visually impressive is far too riddled with controversy and repetitiveness to ever revive its former glory.
As is the case with many blockbusters that make it past the three film mark, the plot of each Transformers movie since the original has been almost identical, save for a few changes of setting and a mix up of cast. None of which have been enough to stop it from heading into the realms of farce, becoming far more recognisable as just another effects-heavy Michael Bay flick than a good movie. Our favourite robots-in-disguise do terrific jobs too as they're almost completely indistinguishable from each other whilst flipping and falling about the screen, save a few unique enough designs like Bumblebee and Optimus Prime.
Putting cinematography aside, the script and dialogue have never exactly been Oscar-worthy themselves. By the second movie, Revenge of the Fallen, audience expectations for gripping, engaging action had been dragged through the mud, to the point where blatantly racist stereotypes and testicle humour had become the norm. They're mindless action and passable as background noise, but the spark has been quickly fading for the franchise.
