In fact, he looks a little weird in the movie, plus his acting is a little wooden, kinda like the modern day Keanu Reeves. Shailene Woodley sucked in the movie either, overall Divergent as a movie failed as a whole, even worse than the Hunger Games.
shareHe acts a little wooden? Duh! Do you see a lot of frivolity or partying going on in Dauntless? His whole leadership role was to mold these naive kids. They were totally new to the concept of "faction over blood". He had to be stoical and strict. Plus, I would imagine that, other than the hippie farmers, everyone had to be super focused/serious to succeed.
His performance was perfect.
What do you got on? Loafers? You don't slaughter animals in loafers!
