Back to the Future Part II

"You have to say it, few movie trilogies are perfect, and if there's a reason why 'Back to the Future' doesn't deserve a place among them, it's because of its second installment. 'Back to the Future Part II' is full of just as iconic moments as those offered by its predecessor (starring gadgets like the flying skateboard and self-lacing Nike shoes), but its script, from the second half onwards, begins to resemble more a rehash of the gags from the first movie. However, Michael J. Fox and Christopher Lloyd's on-screen chemistry as Marty and Doc more than justify this journey full of temporal paradoxes."
