Derek completely let his partner down with that ridiculous Bollywood number (same for the first dance that lacked content as well). It was a cute dance, and Maria performed it well, but it wasn't the dance they were supposed to do. If the Two Stooges on the ends were bona fide ballroom judges like Len, Maria would have been deducted even more points for Derek's showboating mistake, instead of rewarded for it. I don't know if Maria has the fan base to make up for it.
If Maria leaves tonight, I put the blame squarely at Derek's feet.
