... which makes me wonder, when did movie sequel titles take such pride in dropping the number from the title? Isn't it less confusing to have FF2, FF3, etc.? Is it somehow less "cool" to have numbers (Roman or otherwise) in the name? Are they deliberately trying to blur the sequence of the movies in the audience's mind?
It's like the annoying, asymmetrical way the X-Men movie titles go
X-Men: The Last Stand
I remember someone joked that the film adaptation of The Madness of George III was retitled The Madness of King George so American audiences wouldn't think the film was a sequel.
It's not like sequels have to have numbers, but at least some of the ones that don't imply a sequence, like The Thin Man, After the Thin Man, Another Thin Man, etc.
