The Godfather Part II (1974)
Francis Ford Coppola somehow managed to top his Oscar-winning achievements in the original Godfather with this beautifully made sequel, which simultaneously tells the stories of a young Vito Corleone and son Michael.
James Cameron took over from Ridley Scott for this potentially tricky sequel, and came up with one of the best action films ever as Ellen Ripley returns to Planet LV-426 to battle a small army of marauding aliens.
The Dark Knight (2008)
And the three worst
Jaws: The Revenge
Considered one of the worst films ever made, Jaws 4 really scraped the bottom of the chum barrel when it came to plot, as Ellen Brody becomes convinced a shark has followed her to the Bahamas to avenge its fallen comrade.
Full of terrible songs and lacklustre performances, Grease 2 wasn't a patch on its perky predecessor and bombed at the box office. But a young Michelle Pfeiffer emerged from the experience relatively unscathed.
Star Wars: The Phantom Menace
This deeply disappointing 1999 reboot featured a miscast Liam Neeson and a massively irritating animated creation called Jar Jar Binks. The Phantom Menace was a pompous bore, but it made a lot of money.
