Insurgent Teaser

Does tris have short hair in the insurgent book or does she in the movie because Shailene Woodley cut her hair for the fault in our stars? Either way, its retarded. No one like Tris in the first film, and now everyone will hate her. Also, is the trailer telling us the entire plot is Tris saving her mom, who already died in the first films so it makes no sense at all, out of a burning building. I certainly hope not, because that sounds like a boring-as-sh** movie. And are there 2 people in the film? I really expected Four to return, even though he was acted terribly. I also expected Miles Teller to return, who was the only one who did the right thing and call Divergent what it is: an awful movie. The chances of Insurgent being any good are pretty much -400%, and will anyone enjoy this movie?
