Does something look "off" with Mel Gibson's upcoming "Hacksaw Ridge"?

You can saw whatever you want about Mel Gibson. but at the end of the day he was as charismatic as any Hollywood actor that came after him in the 80s and 90s and 2000s. Of course what he said to a police officer inebriated was a disgrace, but can we already get over it? When it comes to actors turned directors he's a keeper. He has directed three films that deserve your attention: "Braveheart," "Apocalypto" and, yes even, "The Passion of the Christ." He's proven with every film that he has acute eye for detail, developing a style of overtly realistic violence mixed with historically important stories. He may not be the most subtle of filmmakers, but he sure does know how to tell a story.

His latest is called "Hacksaw Ridge" starring Andrew Garfield costars with Vince Vaughn, Sam Worthington, Luke Bracey, Hugo Weaving, Ryan Corr, Teresa Palmer, Richard Pyros and Rachel Griffiths. Opening on 11.4.16.

After a couple of views of the trailer my opinion seems to be that they might be selling the wrong movie, or at least I hope so, because that trailer looked to me as a by-the-books, hollywood formulaic war movie. They must have, in all likelihood, "pimped-up" the film to look marketable enough. Am I wrong in being worried? This does come from a fan of Gibson's directing.
