4. 'Back to the Future' (1985)
Funny, thrilling, unbelievably Oedipal: When Marty McFly (Michael J. Fox) travels to 1955 and accidentally prevents his parents from getting together, his mother transfers her affections to him instead. Fortunately, Fox doesn't have to pluck out his eyes — instead, he labors to make his parents fall in love, so that he will actually be born. Best subtle joke: McFly knocks down a tree in 1955; back in 1985, a shopping center has changed its name from the Twin Pines Mall to the Lone Pine Mall.
