If your looking for hardcore action, be disappointed. This isn't that kind of movie. The beginning 5 mins and ending roughly 15 min - 10 mins was the best scenes and visuals you ll see. The movie plot is basically a relationship that bumblebee forms with a teenage girl who is struggles to enjoy life after the death of her father.
The movie does bring a better introduction to the transformers franchise, however sometimes it feels like there was too much of unwanted scenes of connection between the bond of the girl and bumblebee as it slows down the pace of the movie. I do hope that future sequels do bring back the action we love, but not like the last two transformer movies with Mark walberg as they were utter rubbish.
People comparing this to aquaman is just stupid as the visuals are far better along with the story telling in aquaman and both are completely different genres to begin with. So don't compare the two.
Overall a 7/10 movie. There are silly comedic moments which the little ones will enjoy, so it is a watchable and enjoyable movie, just don't expect too much action. Prolly bring them and more characters which were missing in this part (won't mention which transformers are missing as they are spoilers).
