I like the XMen movie. However, the OP says Steinfeld plays Petra Arkanian, Ender's trusted right hand.

As I remember it, Bean was Ender's trusted right hand. Petra was an anchor for Ender's humanity, but it was Bean that was the real military genius, and actually made everything work.

So I'm concerned about how well the movie will reflect the books.

And BTW, contrary to other here, I didn't enjoy the second book, and I really hated the third. But when the "Shadow" books came out, I found them really interesting. I thought it was a great device to re-run the story, but entirely through the POVs of characters who, in the original novel, we thought were nothing but bit players. It challenged my mind to try to resolve the real story between the conflicting perceptions, and I think OSC was trying to show us something about our own personal views of reality.

When you say "Bean was Ender's trusted right hand," I suspect you're thinking mostly of "Ender's Shadow". Reading the original book on its own, Bean comes across as very creative with his small team but not really as a "right hand". (I'd think mostly of Petra and Alai in that role, in somewhat different ways.)

As you point out, there really were some conflicting perspectives (and to some degree even conflicting "facts") in the two stories, and at least for me those "retcons" made the newer book less enjoyable. The few bits of Bean's dialog or internal thoughts that were carried over directly from the original book feel really out of place in the retelling.

I'm optimistic Bean could be a minor character, and then get more screen time in an Ender's shadow sequel. Ender's Shadow was definitely my favorite in the series

Yeah, I'm hoping this doesn't turn into a Star Trek-esque prolonged battle in space. Ender's Game is a character-driven story; let's hope the movie is as well.
