The creators of “Men in Black 3,” opening Friday, hope you’ve forgotten that “Men in Black II” sucked. Regardless, they’ve now got themselves a trilogy — and just like previous threesomes, the third time can either be the charm or just prove that three’s a crowd.

The Hannibal Lecter Trilogy
Anthony Hopkins played serial killer Lecter in the outstanding “The Silence of the Lambs,” then again in the not-as-good “Hannibal” and the middling “Red Dragon.” Sometimes the first bite of something is the best.

Trilogy of the Dead
“Night of the Living Dead,” “Dawn of the Dead” and “Day of the Dead” are George Romero’s seminal zombie films. Everything you know about brain-eaters started here.

Lisbeth Salander
The Swedish trilogy of “The Girl With the Dragon Tattoo,” “The Girl Who Played With Fire” and “The Girl Who Kicked the Hornet’s Nest” makes David Fincher’s “Dragon Tattoo” look sweet and tame. Well, almost.

The Godfather Trilogy
The first film was amazing. The second was even more amazing. We do not speak of the third. We’re not even sure why it’s on this list.

Star Wars
C’mon, you actually thought we’d leave the original “Star Wars” trilogy off the list? Please. Put the angry emails away. We’re going to get enough of them from “Lord of the Rings” fans.
