This movie is Short, whereas the runtime may be about 78 minutes but with credits and an opening "anime"-style intro, it's only approximately 70 minutes long. It's short, which Can work in certain films, the Main issue is that certain scenes that were Crucial in the overall Arc were rushed, badly. Especially one scene with Zod where this took up about 15 minutes in the 1997 series, a 10/10 series by the way, but the Movie made it seem less important than it was. Also, the lines are Very straight-forward, as in telling the audience exactly what happened with no room for interpretation. The Best way I've heard this described is "leaving no room for interpretation and just telling the audience what happened means bad writing," and there is a Lot of that within this film, compared to the series which is just superb.
That being said, it is still a Great watch, especially if you like animation and anime-type cinema, and the story it goes on to tell is top notch... at least the 3 movie series and the 1997 anime which I recommend in English dub over the films; at least a first-watch. If the film was to be a 10/10, it would need to have edited the writing to make it more eloquent, extended the film to about 100 cinematic minutes Minimum, and certain Critical scenes needed to have been rewritten to be more obviously important rather than just line-dropping without time to absorb what was conveyed.
Another great thing is many of the Original English Voice Actors Returned for this film series from the 1997 series! This is just amazing, as it was 15+ years and they came back. This is just Professionalism at its' finest.
