Miles Teller played his rather confusingly static, and then not static character to irritating perfection. Ashley Judd was a breath of fresh air which didn't last long enough. Ray Stevenson was wasted in both films with a boring role which was pathetic and useless beyond a narrative point of view. Thank God for Kate Winslet as Jeanine, the villainess, who brought gravity and depth to a film otherwise filled with young, inexperienced actors and actresses and boring action for the most part. She can play a villain very well, and I found it rather interesting that she reminded me in many ways of a particular US politician; how ironic. Octavia Spencer was also a wasted talent, which is a dirty shame. Ansel Elgort as Caleb (Tris' brother) had potential, but once again there wasn't a lot of time spent on developing his character or the relationship of that character with his sister, which was a real shame as his character turned out to be quite interesting. Since I was rather confused about the entire point of what was going on in the film, I am definitely going to say that the writing and directing was poor; if one has to read the books to really understand what is going on, then that is the mark of a poor adaptation. In both films nothing really else stood out to me except for the costume design which was quite good. The action was even boring; in the first film they spend way too much time in training camp for the Tris character and not enough time developing other areas of the film. Basically, if you never watch these two film you will not be missing a thing; they are entertaining, but I was also bored a number of times throughout both films. Apparently there are two more films in the works and then hopefully the series will conclude.
