From what I understand, they changed and butchered his original script so much that it was barely recognisable from what he wrote. So no entirely his fault.
Yeah, it was apparently supposed to be immensely different.

Cracked had a couple samples (from 6 Famously Terrible Movies That Were Almost Awesome):
Here's how Whedon described it in the screenplay:
"An alien, to be sure, but nothing we've seen so far, its forelegs arch out of its back like spiders legs, its back legs set on enormous haunches, thick and powerful. Its head is long, eyeless, like the others, but along its white expanse red veins, coming out of the skin and running like thick black hairs to the back. It has retracted pincers at the side of head that come out when its tongue does. It's much bigger than the others, nearly the size of the queen herself.
And it's bone white."
"It LEAPS up to the ceiling in a second, quick and effortless as a monstrous flea. [It] leaps again and lands on the screaming soldier ... pincers SWING out and pin either side of his head. His eyes go wide as:
Its tongue SHOOTS into his throat. We watch it drain the blood from his body. We can see it, see its stomach swell, red tinged, as his body goes blue and slack."

In a 2009 Interview with JW:
Q: I thought your original screenplay for “Alien: Resurrection” was brilliant – with its epic final battle on Earth, for Earth – and vastly more engrossing than what ultimately made its way to the screen. I have to assume there were budgetary issues, because I can’t imagine another reason anyone would tinker with it.
JW: Well, let me ask you something. This ending that took place on Earth. What happened in it? Where did it take place?
Q: It took place in a forest …
JW: Yes. Oh, wow. That’s the first one. There were five. And it was always either “the director had a vision” or they had a budget issue. And as a script doctor I’ve been called in more than a few times, and the issue is always the same: “We want you to make the third act more exciting and cheaper.” And my response inevitably is, “The problem with the third act is the first two acts.” This response is never listened to. I usually walk away having gotten one or two jokes into a script and made some money and feeling like I am just bereft of life. It’s horrible. The exceptions were “Toy Story” and “Speed,” where they actually let me do something.
In the case of “Alien: Resurrection,” they decided to spend their money in other places than going to Earth. And I just kept saying, “The reason people are here is we’re going to do the thing we’ve never done; we’re gonna go to Earth.” But there were a lot of things that we hadn’t done that we ended up not doing because of a singular lack of vision.
But rather than go into all of the reasons why “Alien: Resurrection” is disappointing to me, I will tell you that, yes, I wrote five endings. The first one was in the forest with the flying threshing machine. The second one was in a futuristic junkyard. The third one was in a maternity ward. And the fourth one was in the desert. Now at this point this had become about money, and I said, “You know, the desert looks like Mars. That’s not Earth; that’s not going to give people that juice.” But I still wrote them the best ending I could that took place in the desert. And then finally they said, “Y’knowww, we just don’t think we need to go to Earth.” So I just gave them dialogue and stuff, but I don’t remember writing, “A withered, granny-lookin’ Pumkinhead-kinda-thing makes out with Ripley.” Pretty sure that stage direction never existed in any of my drafts.
