Or really, it should be "Part 5, many things happen," but that wouldn't be in keeping with the wedding motif, I suppose.
You know, if this were a normal book, I'd be getting really irritated with just how exceptional everybody is. The Man in Black is practically perfection... and so is the Prince. And even minor characters are the Bestest Ever (except for Westley and the Prince) in some thing or other. And even Buttercup, while not so bright, is the most beautiful woman in the world, yadda.
Luckily, this isn't a normal book. So it doesn't garner much more than a small eyeroll.
And MORE picking at the poor nonexistent Helen. Sheesh. And with Westley and Buttercup one second bickering and being asses to each other and the next minute being exceptionally sweet... argh. Not sure what Goldman a) is intending to say here, or b) thinks he's saying, or what. I don't know if the whole "romance sucks" thing is totally intentional, or is his own viewpoint slipping through, or... I just dunno.
And of course we also have the lovely reunion scene spiel, which according to Wiki Pete is even more bizarreness and faking out the audience. Because just confining it to one book and even one publisher isn't enough!
It's also hard to catch, but the R.O.U.S.'s aren't even explained as Rodents of Unusual Size (I think!) until we actually "meet" them in the book. Which must have made it a bit odd for readers before it was a book (or the very few who might somehow read the book before seeing the movie), but obviously it's an experience I'll never have, to be able to say for sure.
And poor Buttercup isn't really too bright, is she? Although it can be hard to pin down if she's really dull, or if she just hasn't been educated (well, in things other than Princessing).
Anyhow, long story short (too late), Things Happen in this story, Wesley and Buttercup reunite, and are then separated, there is danger and adventure, and more editorializing, yeesh.
So have at it!
