Like I said before, just wait a while. Either this will be like CCS, with new seasons made, or like Fruits Basket, where the anime was dropped in favourof the manga.
Yes, the ratings for this anime are down in Japan...apparently xxholic is doing much better, which is one of the reasons things haven't got too bad for TRC...xxxholic fans are watching in order to keep up with the crossovers. But if the movie doesn't spark some interest soon, I have bad feeling that this great anime will be abandoned at the end of the series.
