This film had nothing to do with the novel, which is extremely disappointing and intentionally misleading. A truly fabulous Clancy novel, Without Remorse would have made an incredible movie adaptation if done accurately. Instead, it's a completely different story line with a weak plot, poorly developed characters and a lame ending. This isn't even remotely based on the book. Even considered on its own merit, the story wasn't original or plausible. Although the acting was decent, it wasn't enough to save the awful screen writing.
