"The teaser of kumari 21F is impressive. top notch work by Rathnavelu sir and DSP. Wishing Sukumar garu & the entire team all the very best :)" (sic), posted Superstar Mahesh, on his micro blogging site this afternoon.These days Mahesh Babu is praising every single trailer and film that impresses. What critics may say, Mahesh recently appreciated "Hero" movie, it's newcomer lead pair Sooraj and Athiya and Salman Khan for launching them. Now that he shares good rapport with Sukumar and Ratnavelu post "1 Nenokkadine" movie, Mahesh haven't got that grudge on them for giving him a flop, but he says it's a collective decision that led to flop and looks into the future.That's so good of you Mahesh Babu.
