Things I like:
At least one character with an emotional stake in the proceedings; something is needed/wanted
A character who is hiding something
Intense focus from at least one of the characters
Something new is revealed about at least one of the characters, preferably a thing that implies many other things
Economy of action: only the actions essential to the scene are described, i.e., those actions that underline the scene's emotional or thematic arc, or explicate character, or both.
What about you?
