When I saw the trailer for this I was geared to see what I thought would be a decent film or at least what you would expect from a transformers movie. I personally do not expect much from a transformers movie just a few fire works, cool effects, and a decent enough plot point to follow, which to me the past 3 did a decent job of just had the film dragged down by either the reach for over-the-top humor or poor acting.
We were led to believe that this was the jumping off into a new direction where the Transformers dominated the screen time vs before where the humans were the main focus. Unfortunately that was not the case as this movie continued to what the past 3 did only worse. Where the past 3 had a plot and a direction this movie seemed to struggle to choose a plot and the dragged it on for 3 hours (2 hrs and 45 mins to be exact). It was like had they chose a plot and developed it the movie would have been easier to follow but they had too many elements going on and did a poor job developing them to where it left the audience scratching their heads.
This movie is a rental and by far the worse of the Transformers franchise. The movie was just too long, recycled many of the effects used in the previous films, continued with the poor human interaction (which at this point I blame the writers and directors and no so much the actors), and just did not have a flushed out story. Both the Dark of the Moon and Revenge of the Fallen had a plot that made sense and had direction where you could follow the story even if Dark of the Moon was too long. In fact if you thought Dark of the Moon felt long then boy get ready because you going to walk out the theater wondering what day it is. Paramount need to hire a new team of writers, producers, and directors to steer this franchise in the right direction. Where this film left off if the studio bring in some fresh minds and change the focus of the movie to the Transformers themselves they could breathe new life into this franchise. If not then the title of this movie fits it well and this franchise is at the "Age of Extinction".
Parental Advisory (Transformers: Age of Extinction (2014) - Parents Guide) : This movie had cursing and crude humor throughout the film and though it did not bother me I would highly advise parents watch it themselves or read the guide I posted in the link above for this movie.
