Annie is such a great musical... unfortunately, this version was probably put together with too little time for the performers to really learn their characters. Even allowing for a stage performance which is normally over the top for television, the majority of the cast, including the leads, never really mastered their characters.
Taraji P. Henson as Miss Hannigan mastered her part for acting and music as did Rooster's girlfriend, Lily St. Regis played by Megan Hilty. Rooster (played by Tituss Burgess) was well performed as a character and was pretty well sung.
All in all, I've seen better performed high school productions of Annie.
