The film shares the relentless breakneck pacing of the Bourne films and similar action thrillers. It is a headlong sprint from start to finish. The other DrC and I enjoyed it.
All four stars do a good job, particularly Branagh who is a Shakespearean actor of note but versatile as blazes. Remember his smarmy over-the-top Professor Gilderoy Lockhart in Harry Potter and the Chamber of Secrets?
BTW, am I the only one who wonders why Keira Knightly doesn't have her teeth straightened? She's cute in spite of it, which is perhaps the idea, but it's vaguely distracting. We're accustomed to screen personalities being more-or-less flawless.
