Zumba fitness for Wii. Any opinions?

I have it and definitely recommend it! I don't use it yet as often as I'd like, but when I do I like to alternate between 2 Zumba songs and 8 minutes on my stationary bike for about 40 minutes that way I can switch it up without getting tired of one or the other and can keep my stamina throughout the entire burn. The quality of the game is so-so, but it's great because you can set goals for yourself on it and it also tracks approximate calories burned in each song you've danced to. It is as fun and intense as you make it-- wonderful at-home alternative to the typical Zumba classes.
