I love Transformers, I grew up on the cartoon, and I have enjoyed all of the live action movies, even when it was unpopular to do so.
The film starts on a jungle planet which long ago was colonized by Transformers, the Maximals, an advanced race of Cybertronians with beast modes, (instead of transforming into cars and planes, these guys transform into animal like robot creatures) find their home world under attack by Unicron, a malevolent deity who consumes entire planets. Leading the charge are Unicron's heralds, the Terrorcons, and an army of Predacon drones commanded by Scourge (Peter Dinklage). Their objective is to seize the Transwarp Key, the Maximals' most powerful piece of technology capable of opening portals through space and time. In a selfless act, Apelinq (David Sobolov), the leader of the Maximals, sacrifices himself, allowing his comrades to escape before Unicron devours their planet. Now under the leadership of Optimus Primal (Ron Perlman), the Maximals utilize the Transwarp Key to seek refuge on Earth.
Rise of the Beasts is the seventh film in the franchise, it acts as a standalone sequel to Bumblebee (2018), and as a prequel to Transformers (2007). As long as you have a general understanding of what a Transformer is, you can watch this film, without ever having to see any of the other films.
