Give Princess Nine a chance--after four episodes you and your whole family will be hooked. The basic plot is that the principal of a girls' high school wants (for mysterious reasons of her own) to put together a girls' baseball team to compete in the boys' championship tournament.
You do not need to be into sports drama or girls' shows to love this series. You just have to love great characters and great storytelling. The characters are the real strength of the show: for example, the 'antagonist' Izumi is one of the most compelling and complex characters I have ever seen on television, animated or not. I could understand each character's motivations and fully understand (but not predict) their behavior. Some of the minor characters are a bit one-dimensional, but they all get at least one great moment in the sun. P9 may have the best original score of any anime I've seen, except maybe Cowboy Bebop. The animation is not of the highest quality, although the character designs are good and they put in extra effort for the important scenes and Ryo's crazy pitches.
P9 has all the sports drama you could want, including different strategies for each game; a drunken lazy but brilliant coach; a love triangle that is actually interesting; and a great "putting-the-team-together" sequence. It's inspiring and positive, but never preachy, and it's not afraid to get into some interestingly dark emotional territory. The ending is absolutely perfect, which I have never seen in anime.
Again, this show is NOT just for sports fans, or for fans of girly anime: it's for anyone who likes a great story and amazing characters. There's very little that could be called "fan service," especially considering the opportunities provided by the setting. Adults and kids of both sexes will enjoy it--my son (13), daughter (10), and wife all loved it--but ideally the kids should be old enough to read the subtitles (if they don't speak Japanese), because the English dub is **far** inferior in quality to the original Japanese voice acting. Sorry to be a subtitle snob, but without the subtleties of the original voice acting it's just not the same show.
If you love great TV you cannot go wrong with Princess Nine. Get over the title and check it out.
