Stardust - Needs a third act?

So, I'm thinking the upcoming film adaptation of Neil Gaiman's Stardust is going to suck:

A few months ago, it was announced that Vaughn would also produce and direct an adaptation of Neil Gaiman and Charles Vess' graphic novel Stardust sometime after he finishes X-Men 3. "I've written the treatment, but I'm not a writer, so I'm just trying to find the right writer," he updated us. "Obviously, to make it into a movie, I have to change it a bit, and put a new third act on. It's going to be cool, sort of like 'Princess Bride' meets 'Midnight Run'." Vaughn mentioned that he has some limited edition art that Charles Vess sent him, but that his movie would look somewhat different. "The way he paints is very Victorian in a way, but I want it to have more of a modern look. I think the problem is that when people say 'we're going to do a fairy tale, so therefore, let's shoot it in a fairytale way.' I wanted to shoot it more modern and grittier."

Oh, and dude, this just makes you sound like an idiot:

"I like comic books, but I don't read them like I used to," he told us. "I quite like graphic novels more than comic books."
