I think it's too sad.

That's U+1F615 CONFUSED FACE - it's not supposed to be sad.

Android and Symbola render it with a straight, slanted mouth - I'm not sure why other fonts make it sad looking.

Of course, the slant of the slash in any given font could alter the meaning too :).

That's sad, not neutrally unsure or puzzled.
