ALIENS (1986)

A bombastic, action-packed sequel that has basically nothing in common with its tense, contained thriller of a predecessor, and yet both are great movies in their own way.

STAR TREK VI: THE UNDISCOVERED COUNTRY (1991)

Christopher Plummer’s Shakespeare-quoting Klingon general is one of the many highlights of this final “Original” Star Trek movie.

THE GODFATHER PART III (1990)

Francis Ford Coppola recently released a re-edited version of the least-acclaimed film of his famous mafia trilogy, but how much of a difference does it make?

THE GODFATHER PART II (1974)

This all-encompassing sequel involves at least two separate movies that never quite meet.
