Understanding the plot line was nextcto impossible. A lot of action,but .....why?

Worse movie of.the franchise.

Not my cup of tea!

It was terrible. Hard to follow, too many unfinished plot points. Broken physics, and absurd wartime management of resources on both the military and transformer sides. And there wasn't nearly enough transformer fights! no iconic "Autobots, roll out" This was one of the worst movies I've ever seen
