Is one of those the apocalyptic "I'm bleeding to death here in our
bombed-out apartment, let's have sex" story?
Five minutes of my life I'm never gonna get back. 
Actually, I kinda felt the same way about it. I haven't seen the finished product, but most script readers only read the first...ten pages or so. If they find fault with it within those first few lines, then...*finger across throat*. That was far too...*blinks*...I don't want to say cheesy, because that's rude. Hackneyed would be the word I'm looking for. For Delicate, Ugly, I could have gone without the lazy, silly sex stuff. I love post-apocalyptic stories, so you were
sorta buying me (on the story, not the dialogue) up until that point. Then it just got...ugh.
The Mortician's Daughter...I didn't make it past the first two pages.
Butterfly, I didn't make it past the first five pages. Then again, I was major sleepy by then, and didn't want to read that much.
The Last Rope....was also a bit hackneyed, BUT it was the only one with a story I was interested in. I wanted to find out wtf was going to happen to Syo, and what had happened to the other brother. I figured sacrifice, but I wanted to see how the sacrifice played out, and what the curse was all about on their village. I didn't finish it, merely because I wanted to finish the others.
I think, and this is just me, that if you cut all the filler lines, and the sappy-soppy love bullshit from the first five-six pages on The Last Rope, and actually work on it, you've got a story today's audience might enjoy.
Also, as for the overall ability to write, I think you need a lot more work at writing dialogue. It's very hard to write a script, because in a script, you have to actually create people, make them interesting, and then make them believable without being realistic. If the dialogue is bogus, nobody is going to like your script, regardless of how great the story might be. I used to love writing screenplays, until I realized I sorta sucked at dialogue. I've improved since, but really...I mean...*finger down throat*...it hurt. Even now I've adapted a style in my storywriting that makes the plot/setting/action the focus, and not the dialogue.
Anywho, keep writing. =D
