No shaping up. They've totally screwed up her character. This is entirely Chulbul's film. Saiee would be presented the way Sona was presented in Dabangg 1.
If they had understood the character of Rajjo, they wouldn't make her dance like this or even behave like this. There was delicate detailing in Dabangg 1 which Dabangg 2 took forward. Except for the bit where she danced with Munni in Pandeyji Seeti song, she was never made to break character.
This is for namesake Rajjo. Rest all is Prabhudeva's idea of heroines. You can see the same stuff from Action Jackson's Sona or Rowdy Rathore's Sona. These promos showcasing her has zero grace of Rajjo. Sonakshi could do nothing here when she hasn't given much choice. Hopefully it is only in the songs Sonakshi's Rajjo breaks character & not in the screenplay.
