The most ridiculous scene in this movie, no joke.
At the start, Selene (the protagonist) is cryogenically captured by humans, but she breaks free. She ends up in a locked room, and notices the man who put her there (the antagonist) watching her from a windowed station above. They lock eyes, and Selene visibly fills with rage. Her reaction?
She kicks over a chair and marches to a corner of the room.
Why? I'm not sure. She literally walks over to a corner and pouts, while the antagonist orders his lackeys to gas the room and leaves. As Selene notices the gas, she remembers that she is in fact a vampire, and leaps through the window. She easily murders the lackeys and escapes, missing the main bad guy by mere seconds because the director had no idea what to do with her.
I saw this movie when it came out and I forget almost all of it, but this scene is burned into my brain through sheer idiocy.
