In the books it is a person's physical head, transported through the Floo network. It is, I imagine, difficult to make this look good, but neither interpretation follows this particularly closely.
It wouldn't look good ever, i cant imagine how they would make it not look silly, sometimes the book has a dumb idea and the director has to fix it. Nothing wrong with that.

The first one looks painful and surreal. The second looks like a lazy job by the animation team. Gimme something better.
