Helicopter evac?

Rating: Null/10 (12 September 2016)

Contains spoiler.
I thought the set up was good.
The middle was OK.
Ending kind of meh.
What was barking at Thomas as he comes up in the evlevator in the opening scene? Oh, its just a wild animal in a cage used for a quick jump scare that we will never see again all movie.
And why doesn't the search and rescue team that saves the Gladers at the end just land a helicopter in the middle of the glade?
