Our take on Back to the Future Part III

Robert Zemeckis's 1990 finale digs the trusty DeLorean out of a mineshaft and drops Marty into the Wild West of 1885 to rescue a stranded Doc. When the time machine breaks down, the pair are marooned among spurs and saloons, while Doc falls for schoolteacher Clara Clayton and Marty squares off against the volatile Buford Tannen. Closing the trilogy, it swaps sci-fi gadgetry for affectionate western pastiche, leaning on warmth, humor and adventure. It suits fans who've followed the earlier films and want a sentimental, good-natured send-off, plus anyone who enjoys genre-bending romps. Newcomers should start earlier; devotees will find a fitting farewell.
