I loved Tom Clancy books and movies growing up and I always wanted them to make Without Remorse into a movie since the book was so good. I was thoroughly disappointed. The only commonality are some of the characters and the title. They could have just changed the character names and the title and not claim this to be a Tom Clancy film. Either stick with the plot of the books and do them justice or don't claim to do a Tom Clancy film. The plot they did use instead was stale and not what I would expect for a major release. It was more in the direct to DVD league.
It also seems like they did not have very good technical advisors... or geographers. The opening scene takes place in a landlocked city and yet Kelly and his team infiltrate via water. The uniforms are also very inconsistent... Greer is wearing a commanders cap in at least one place which is different than what her rank would be. Since the writers took so much liberty with realism, they just wrote her in as a SEAL instead of a more plausible role like being some sort of subject matter expert attached to Kelly's team. I'm not one to dismiss the idea that there are women out there capable of becoming Navy SEALs, but I would expect the to be built like a crossfit games winner instead of the stereotypical model. I know this comes off as nitpicking, but the filmmakers should know their audience. Tom Clancy's books and previous films were always very detailed and realistic and this film was far from that.
The one positive part of the film was Michael B. Jordan's performance and the only reason I gave this any stars. I was excited to see him in the role when it was announced. He did well with what he had to work with. It is a real shame. Had they stuck to the plot of the book and took the details seriously, I would be excited for Rainbow Six. Now I just hope they forget they planned on doing it.
