Det. Supt. Jane Tennison (Helen Mirren) is weeks from retirement, worn-down, and alcoholic. 14 year old Sallie Sturdy goes missing. Principal's daughter Penny Philips is her best friend. Sallie's father is faced with suspicion and then her body is found. She was pregnant. Tennison's father is in the hospital "on the way out" with cancer and she is pushed to go to AA where she runs into Bill Otley.This is a great final act for a great character played by a great actress. Tennison is beset with personal problems that are well earned. Bill Otley returns to tie up his relationship with her. It's a short reunion but a very powerful one due to their history. He's also given a terrific death. Another great relationship is Mirren with young Laura Greenwood who plays Penny. She is almost like a daughter that Tennison never had after her abortion. The final scene is an emotionally devastating conclusion to Tennison's career. Greenwood is incredible in the face of the legend next to her. The second part does have a slow spot in the middle and the last section does rush a little to the finish. However, the final interrogation cannot have ended the franchise any better.

2007 Emmy Award Winner for Outstanding Directing for a Miniseries, Outstanding Lead Actress in a Miniseries, and Outstanding Writing for a Miniseries, Prime Suspect 7: The Final Act is as dynamic, brilliantly written, directed, paced, and acted as the rest of the series that started in 1991. The Final Act is filled with the unexpected plot turns and introduces interesting complex characters. Prime Suspect 7 was dedicated to the memory of Tom Bell (Otley) who returned as Sergeant Bill Otley and who died two weeks before the episode was screened. As in all Prime Suspects, Helen Mirren owns the screen as Detective Superintendent Jane Tennison working on her last case before retirement. This time, Jane investigates the missing of a 14-year-old girl while struggling with her alcoholism and coping with her father's death from incurable cancer. She dedicated all her life, talent, energy, and heart to her work where she had proved to be the best but the price she paid is incredibly high. The Final Act introduces a young actress Laura Greenwood (born in 1991) as 14 years old Penny. The scenes she shares with Mirren are "nothing short of phenomenal," according to David Bianculli of the New York Daily News, and I hope that her following roles will be as impressive as her first work next to one of the greatest modern actresses.9.5/10

Dame Helen Mirren ends perhaps her most famous role besides that of Queens. Jane Tennison DCI is one of the most original female characters that television has produced in recent years. She is almost unforgettable. When Dame Helen Mirren first started, few people knew who she was and now everybody knows in the world that she is one of the finest acting talents from Britain. I knew she was in 1986 when I saw her play a maid in a Titanic film. As Jane Tennison, Helen Mirren embodies the role with such complexity that it seems so easy and natural. Jane approaches retirement with one last case but you know that Jane has lived for this job. They have this marriage between them. In the final installment of this legendary series, Helen and Jane bow out gracefully in the end. Jane battles alcoholism, loneliness, and her father's pending death. She reunites and befriends AA member, Bill Otley, played by Tom Bell shortly before his death. I felt the parents of the missing girl were quite believable in their roles. Jane's pending retirement is beset by loss, wonder, and disappointment. In the end, she bounces back, makes a shattering discoveries about the case, and you wonder what would happen to Jane Tennison that you want more. Maybe she is lecturing on crime techniques at a university or other British police officers. One can only hope that this is not the last we see of Dame Helen Mirren as Jane Tennison.

The original 'Prime Suspect', an unusually tough police procedural thriller, was a landmark in early 1990s television, immediately making other hits series like 'Inspector Morse' appear tired and out-of-date. Since then, the series has retained some quality through its relatively infrequent outings, but still, the writing has not always been as good as in the first episode and in some cases has lapsed into the melodramatic cliché of the standard crime show. Gradually, I lost interest (I think about the fifth time that the whole direction of central character Jayne Tennyson's life was on the line if she didn't solve some murder in the face of the scepticism of her colleagues). But the series has always featured great acting from the incomparable Helen Mirren in that role, and in this final part she has arguably never been finer, there is some longer-term narrative development from the earlier episodes and Mirren exploits the character's growing history as the basis for a harrowing, wholly three-dimensional performance that almost seems out of place in a crime drama. Behind her performance, there's a nicely executed but less extraordinary tale of murder that could have come from any other cop show.What's amazing about Mirren is how she truly inhabits the parts she plays: having recently seen her in Channel Four's 'Elizabeth', one can say the two series constitute a masterclass of televisual acting, ancient and modern. The series may be done; but the prime of Helen Mirren is far from over.
