The writing was just painfully awkward. Quoted from the linked MST3k that CJ posted.
Ugh, what? Air filtered down? Don't you mean 'light'?

The hippity-hopping around like crazy makes me psyduck. One subject, new paragraph, please.
Can you spot all the Mary Sueisms?

I can't take credit for all this - it's all just tweaked from the linked blog, but seriously, it explains itself.

Obviously they are in some sort of space jungle, and physics is special here so air is sucked in to fill the vacuum, it just filters down.

It's cuz of the vampires. All vampires have magical jungles on the moon.

Has the air been eating chlorophyll?

I was kind of wondering how it could be 'filtering greenly.'

Stephanie Meyer didn't read that sentence aloud; that's how.

I told you, it's a magic jungle. Thus the air is magic, too. If the vampires want green air to filter greenly into their magical jungle moon base, who are you to tell them otherwise?

To further pick that paragraph apart, "greenly" is a word that should never, ever be used. How does anything do anything greenly? It's a feeble, non-descript description. Even regular adverbs look down on that one.

Let me suggest an alternate phrasing. There was only so much to say about the weather, after which we stared out the windows in silence. I couldn't deny it was beautiful. I had never thought there could be so many shades of green: Thick layers of ferns covered the ground. Ancient trees, crumbling, twisting under the growth of moss; the sunlight shining through the leaves seemed to make the air itself green.

Now, I hate to admit it, but one of the things I'm hating about Stephenie Meyer's writing is that we share several of the same weaknesses of writing. Especially Show vs Tell and the fact that if I thought about it, most of my character's are probably unintentional Mary Sue's. God. I know my weaknesses. I have a hard time working around them, and I tend to forget them, but I try. It in no way makes me happy to see someone getting rewarded for doing everything that is wrong with my writing. It pisses me off.

This is an improvement only in as much as one can improve shit by making it a more agreeable color.

I'm not saying it was a bad attempt, by any means, merely that the material you are working with is just nigh irredeemable.

Well, you could recolor it, fill it with so many sweeteners the smell goes away, throw in some gelatin or something to alter the texture, pump it full of vitamins, bake it to kill the bacteria, dip it in sugar and you'd never know it was shit.

(Yeah, I think I'm that good. :D)

Dude, everyone starts out somewhere. Advantage is you and me aren't going to shit out an awful Mary Suefest and become best sellers and have a movie made after our craptacularity.

I mean there's being bad and then there's being bad yet inexplicably famous.
