First Transformers: The Last Knight trailer is dark and confusing

Well, that was certainly something. Not content to leave the series as he claimed, Michael Bay has returned to direct Transformers: The Last Knight, a movie featuring a very serious plot about very serious things. But will also at some point feature King Arthur and his knights. But as what we can see in the trailer, Mark Wahlberg returns to the series as he’s being hunted down by Transformer elimination squads.

I have no idea what’s going on in this trailer. Was that Unicron? Why does this look like a colorful Terminator? Why the hell is Anthony Hopkins here? 

Transformers: The Last Knight releases June 23rd next year.
