Too fast. Everything seems so rushed. It's not like its a massive book but I've realised how dense it is and this movie suffers.
If you've not read the book if be interested to know what someone thought but as fan of the Ender series..this is pretty average.

Excellent book, very weak movie.
There is no emotions or high points at all.
What a disappointment...

All the events in the movie moved way too fast, seemed like the movie runtime should have been twice as much. Because of that rush the story is not clear to follow. Thumbs down for me here.

Just ok. Great visuals.

Really awful, no character development, super weak plot

I’ve not read the book so I don’t know how much they had to condense to make the movie but I think they captured a jewel of a concept. Is the right course to decimate to survive or is there a greater way? If we choose the first course is there anything left of our humanity worthy of survival? I imagine this was a great book, it made Orson Scott Card a New York Times bestselling author and went on to become a classic Hugo and Nebula award-winning science fiction novel (I must see if I can find it as an audible book). The movie aged the main character from a 6 year old boy to a teenager, which was probably necessary for practical cinematic demands, as well as to make a character to which an audience could relate. The casting and performances were good. The CGI was convincing. But, my high marks are for the premise itself, well executed. I give this film a 9 (compelling) out of 10. [SciFi Action Adventure]

I've just watched Ben Kingsley using a South African accent saying he was Māori (complete with ta moko) fighting aliens with children :-(

The whole time watching this, I had the feeling that there was a much better book behind it.

As a sci-fi film in a vacuum, it's competent but flawed in places and has a very uneven and badly edited narrative flow.

I love this series more than I can explain, in fact it is my second favorite Orson Scott Card series, outside of the Alvin Journeyman series; I only add this to say that the review below is based on the movie, and me forgetting the books exist (and yes, I had read them first).

I find the movie fun, it brings a new spin to futuristic space warfare, and I really think the movie was fun, as a standalone film left on a cliffhanger. I really wish they would have followed this up with the true meat of the series... What happens with the egg? But since they jumped the shark real quick, I get not pumping more money into it.

This movie is only about 10% of the book. Even without all the stuff back on Earth, there is just not enough runtime to properly portray Ender's genius (as well as the other kids), the psychology of the training, and the torture Ender goes through.

It also under sells the brilliance of gifted children, the exact thing Orson Scott Card wanted to portray with the book.

Some of the changes to the plot also weaken the overall story. I'm especially not a fan of the very end. Completely unnecessary change/addition.

This really should have been given a multi-movie treatment. It is one of the greatest works in science fiction and it was treated like some YA novel.
