I enjoyed it when I saw it. I saw it some weeks ago with grandkids. One of them knows everything there is to know about the Transformers universe and was informing me of what was right, what was wrong, what differed, what didn't, what was associated with the American version vs. the Japanese version (yes, did you know that apparently there was a split for at least a little while where the Americans and Japanese had two different series that were separate in their chronologies and events?).
I don't know enough to say what is where regarding Transformers, but I have several people close to me that are pretty expert on these matters.
They seemed to enjoy it as well. I've mostly seen the movies, and of the movies I'd say this was my second favorite of them (favorite being Bumblebee).
