Finally saw the film properly via Paramount+, and I share a lot of similar thoughts as others; but if I may I would like to compare this with another film. In that,
Transformers: Rise of The Beast, is this year's Godzilla: King Of The Monsters. It is a very great Transformers film, not the best of the series still (that goes to BumbleBee); but it is a "good" blockbuster. Not great! There are a lot of editing choices and sound mixing choices that are very weird, the abundance of Autobot time compared to Maximal and even Humanoid time is a bit jarring, and the film didn't really have that human connection that BumbleBee has.
But where it excels at, is when in the perspective of someone who adores the series, who wanted to see this kind of film finally handled. And while I am really hopeful in what comes next for the timeline, I wanna see where they go with how they tell Optimus and Megatron's story in Transformers: One. I wish we got more proper decepticon elements in this film; besides the collection Scourge has.
On a normal GP level, probably a comfy 7/10. As a Transformers fan, 8/10.
also Pete Davidson's Mirage was the best Autobot in the film, better than Optimus *runs*
