Cliched lines (from most to least):
I'm sorry, but I can't let you stand in our way.
You're helping destroy the world. What happened to you? (mostly just the "What happened to you")
You can never understand what I've gone through!
We'll do it together, just like old times.
it's like Spiderman 3 all over again!
Don't get me wrong, I can see that you have your own original ideas and themes. It's just too Hollywood-esque. Don't change your ideas, just how you present them.
Perhaps draw more on their emotions, and make stronger statements. Like at the end, the one guy's anger just kind-of vanishes into "I,m sorry, blah blah blah". Keep it going!
Also, E-min has some major mood swings.

"What happened to you? Have you gone mad" to "I can't understand, let's do it together" to "you're no better than..."
I mean, this guy needs a definite attitude. He acts like he has multiple personality disorder.
My synopsis: Focus the personalities of the characters. Then, let their personalities shape the dialogue. The more of your characters moods and feelings you put in, the less cliched I think it will be.
