They finally put Shakaar on the screen again and there's really not a whole lot going on with him. Irks me a little, as does the obviousness of how much more could have been done with the Odo-as-a-solid story.
Despite all that, I'd have probably gone with three-and-a-half stars for this one. As apenpaap
has mentioned, Auberjonois' acting is spectacular here, and his relationship with Dr. Mora is also more interesting, I think, than with the second-season outing.
