Marty and doc are back, but in another time. They go to the West in 1885 in order to save Doc's life and from then on the Western adventure takes place. It's a pity that so many people disliked the third movie because, in my humble opinion, it's a great finale to this fantastic trilogy. It is very well written with rich characters and clever dialogues. This third part does differ in the sense that it's set in the West and has less of the futuristic gadgets and gizmos (obviously, since it's not set in the distant future but you'll still see a few including a time-travelling freight train) but it still retains the same energy, a different kind of action and it pays a nice homage to Western classics. Fox and Lloyd continue their roles of the teen hero and the crazy doctor (and it never gets old) but this time there's a new female lead. Mary Steenburgen delivers a hilariously wonderful performance as the ditsy Clara. She and Lloyd are funny and sweet together. Clara is the perfect lady for Doc and Steenburgen fits the part like a glove. This time, Lea Thompson appears as an Irish settler. Zemeckis has brilliantly picked up from where the second one ended. The film ends on a delightful note and I would have liked to see more 'Back to The Future' movies. But, I'm still very pleased with the way it is. There have been only very few trilogies that have impressed me overall. My list includes names like Ray's 'Apu Trilogy' and Coppola's 'Godfather' trilogy and of course Zemeckis's 'Back To The Future' movies.
