I don't understand the negative reviews. Watched with friends and all agreed that the story is more relevant now than when it came out two years ago. Mark Felt was a courageous hero in his commitment to getting the truth out, despite the tremendous personal risk. Liam Neeson's performance as Felt was credible and flawless as a career FBI agent. Feel that Robert Mueller is out of the mold that Felt exemplified, that of integrity and sense of higher purpose. The overall production of the film, actors and directing, was extremely well done. If the film fell short in including greater history of Felts family, specifically his wife and children, that is a minor flaw compared to decisions to focus on the political climate, agency and corruption that he exposed.
