Courtroom dramas are interesting and this one is a fine addition. Nothing that fancy or over- stylish, it's basically very straightforward and has a simple style. But, that's OK because it works for this film. It doesn't try to be anything it isn't. The scenarios and the dialogue is all very well handled and thought out. It makes you think twice a few times as well.
Some scenes really work and have great tension and intrigue. Especially whenever there is a court scene. Some aspects would have been nice to have seen explored more like when they explain how to tell if someone is lying when testifying.
Keanu Reeves does a good job here and isn't so stale like some people like to say he usually is. There might be some truth in that for some films, but here you can see that he stepped up his effort. The role was originally set to be played by Daniel Craig, and I can definitely see how his acting style would have worked well for the character. It's a shame he dropped out last minute, but Reeves makes the character his own and you can understand his motivations.
The ending was unexpected and included a strange little twist which the movie could have done without and still worked well and perhaps in some ways been more effective.
The film is interesting if you want a mystery with some turns and it has some captivating courthouse scenes which are in some moments disturbing.
