Back to the Future Part III

Back to the Future Part III is a 1990 American science fiction Western comedy film and the third and final installment of the Back to the Future trilogy. The film was directed by Robert Zemeckis, and stars Michael J. Fox, Christopher Lloyd, Mary Steenburgen, Thomas F. Wilson and Lea Thompson. The film continues immediately after Back to the Future Part II.

Plot
In the final chapter, Marty McFly (Michael J. Fox) obtains a 70-year-old message from the time-traveling Dr. Emmett Brown (Christopher Lloyd), to 1885, in which he informs Marty that he has retired to a small town in the Old West. Marty then finds out that the Doc was murdered shortly after sending the letter. In order to save his friend, Marty will have to travel back in time, disentangle a lovestruck Doc from a local schoolmarm, and repair the DeLorean -- all while avoiding a posse of gunslingers.

Why It's The Third Time For Time Travelers

 * 1) The film is a well-written, well-directed, and well-balanced piece of an already successful trilogy.
 * 2) An original, creative plot with that went from the sci-fi futuristic plot of the last film into a spaghetti western a la A Fistful of Dollars.
 * 3) Robert Zemeckis and Bob Gale, the masterminds of the first and second films, returned to write and direct.
 * 4) Alan Silvestri's beautiful score, in which it was scored back to back with the second film.
 * 5) Michael J. Fox, Christopher Lloyd, and newcomer Mary Steenburgen are excellent as well.
 * 6) Excellent composition and scenery.
 * 7) It was a return to the basics, the friendship between Marty and Doc and how each was thrown through time to change not only the future of Hill Valley, but also their own lives and their future choices.
 * 8) The film brilliantly concludes itself and the trilogy it built as a whole.
 * 9) Although on the surface it's a lighthearted comedy about time travel, it's also about what it means to be a man.

Bad Qualities

 * 1) Some of the 'natural' set pieces of 1885 Hill Valley aren't that good.
 * 2) Douglas Needles does appear from the second film, and still barely has any character development or screentime.
 * 3) In the ending, Doc Brown's younger son Verne directly points at his... flux capacitor. Granted, the actor might have wanted to go to the restroom, but still.
