Sequels are generally less highly-regarded than their predecessors. Any wiseacre can find you a few films with ‘2’ in the title that improve on the original, but it’s even easier to find a whole lot more movies that don’t.
Fantastic Beasts isn’t a movie sequel per se. It’s the start of a new franchise that is effectively the follow-up to the Harry Potter series. In fact, by virtue of its late 1920s setting, it’s a prequel to the whole thing.
The question many moviegoers might ask is: ‘does Fantastic Beasts require a working knowledge of JK Rowling’s wizarding universes?’
The answer to that is “no.” I’ve managed to get to the end of 2016 without ever having read one of the books or seen more than a few minutes of the films. There are occasional little references to characters we’re clearly expected to know but this is a film that happily careens along on its own merits.
