First of all I must say I was a big fan of transformers prime, and was my introduction to the transformers series, I watched the animated and the Michael bay movies but they really couldn't catch me the way prime did, and after having to endure years upon years to finally get me a hbo max account I must say it was well worth the waiting, that said, this movie, as the ending of the beast hunters saga, was a disappointment, I don't know the behind the scenes of the production but you can tell it was not only rushed but it was gutted as well, the first half hour of the movie was not only on par with the series at its best but even managed to surpass it for a moment, but afterwards it quickly became clear there was a shift during the production of the movie, as at least one third of the entire runtime seems to have been taken away, and the writers seemingly had to panic and scramble ideas to tie up what's still left of the movie, ideas had to be abandoned, plot points scrapped and recycled and the ending had to be rushed, at the end, there was no beast hunting, no (alive) predacons rose up, and no epic battle between our three main players, with the ending being as close to a deus ex machina, even if it ultimately (kind of) made sense given the situation. It left me wondering what happened behind the scenes more than what happened on screen.
It was okay, you should watch it.
