As a long time John Constantine fan, I started reading this, Christy, but I had to put it down after a few pages. Your formatting is completely off, making it very difficult to read.
Your header was improperly done. Instead o:
BEACH FRONT SHACK WITH CHARM
you should write:
EXT. BEACH FRONT SHACK.  
AY
and then describe the scene in further detail.
You shouldn't list any songs you want played; it's not your job to pick them. And never write the songs out. No one wants to read songs when reading a script; they want to read story.
When writing the narrative/descriptions in a script, you only should write what the camera can record, basically, visuals and audio. On the bottom of page one, you wrote:
Her stares out towards the sea and does a double take when
the thin air shapes into the form of a gorgeous black male,
ripping chest and abdominal muscles with a rogue smile smiling
lust and desire. The potential for wanton and exquitisite
satisfaction. She is completely taken in by his smile and
physics that she forgets the impossibility of what she just
saw actually happening. (We on the other hand know that we
are in the company of Satan.)How does the camera record the whole physics and impossibility thing? He must have a helluva smile!
We, on the other hand, know we are in the company of Satan? How do we know that? Obviously, the guy who appears out of smoke is not your normal guy, but we don't know who he is. John Constantine's world is filled with demons and other magical creatures. How would we know that this one is Satan?
In the second page, you describe him as changing into the:
form to the last we saw in Constantine. White man, white
suit, leacherous smile.If someone reading this script didn't see the movie Constantine, then they have no idea what you are talking about. And you've lost them. When writing a sequel, you have to assume that no one saw it. Telling us that we know things from part one doesn't wash.
I got the impression, from the few pages that I read, that your only experience with the character of John Constantine is from the movie. I've read practically every comic book that the character appeared in and I don't believed that God ever shows up in a story. He usually sends his angels to Earth to serve him.
On page four, you wrote that John is not gay. In fact, he is bisexual.
I suggest you hit the comic shops and pick up some copies of Hellblazer and learn what John is really like. Writing a sequel to a really bad film is not a good thing to do.
Also, read some scripts here and learn about formatting. See what to include and what to throw away when writing a scene.
