Inside by Steven J. Fauquier - Thriller - After a night out, a couple comes home to find their front door wide open and are convinced that their is someone or something in the house waiting for them. - html** format.

Hmm...I'm kind of 50/50 on this one.  I'll see if I can break it down...

Dialogue - really good, for the most part.  I liked the repoirtee(sp) between your two leads.

Action/Description - could use some tightening up.  Lean more towards present tense verbs, it makes things less wordy.  Also you need some work on syntax, but nothing that's so bad it can't be easily fixed.

Story - Some extraneous stuff in the beginning but it gets better.  You drudged up some nice tension there, kudos on that.  

My Complaint - The big revelation at the end...damn, how to word this without mentioning specifics...there's no hint of it throughout the entire script so it seems added on just for pure shock value alone and I find it difficult for Carl to not have known that one thing, particularly after you've presented them as a very intimate couple.  Carl would have to be blind -- or straight-up dumb as a hammer -- to not have known that one thing.  Also it would be obvious to the viewer when we see Andrea running about the neighborhood.  

Maybe if you'd made like there was something she wanted to tell him early in the script but couldn't for whatever reason, THEN the big reveal, it might have worked.  But as is, it comes from way out of left field.

Other than that, some easy-to-nip-and-tuck segments aside this made for a decent read.  I just can't stress enough how implausible that one thing is.
