I get the concerns from posters above, but we could have a chance at getting a very tense and suspensful movie, with survival based on the wit and cunningness of the characters, especially with them being younger but knowing the terrain and surroundings by heart. We haven't got that since forever.
It totally could work and be awesome. It also totally could be shit. I choose to wish for the better obviously, but with the little we know now, there is still hope. And potential concerns that are not to be overlooked either.
