Telugu Cinema from 2010 to 2019 saw consolidation of Mahesh Babu, Pawan Kalyan, Jr. NTR, Allu Arjun, Ram Charan and growth of Prabhas, as big stars.
Allu Arjun found Race Gurram, Sarrainodu kind of hits adding to the market growth he enjoyed with Julayi. Now, he is one of the big stars but he has big flops like Naa Peru Surya, Badrinath to call him Star of the Decade.
Mahesh Babu found form with different films but during end of the decade he acted in very routine characters and that affected his market. But he has 50-50 success ratio with disasters like Brahmostavam, 1Nenokkadine and Spyder which lost more than what his hit films earned. Dookudu and Srimanthudu did increase his market and we hope he finds consistency in 2020's.
Pawan Kalyan started off the decade with disasters, in the middle scored Gabbar Singh and Attharintiki Daredi kind of big hits but again delivered disasters like Agnyathavaasi, Sardar Gabbar Singh to keep his success ratio at minimum like 2000's after Khushi.
Ram Charan managed one big success with Rangasthalam but immediately delivered a flop like Vinaya Vidheya Rama. He found more consistent success as producer with Khaidi No 150 and Sye Raa.
Jr. NTR started off the decade by changing his style with Adhurs, Brundavanam and went back to routine films to damage his market. But from 2016, he found films that continuously increased his market while 2014 Temper, changed his image for good. Still, his films are said to have fallen just short of Break-even status and hence, he cannot be given Star of the Decade title.
Prabhas could have easily taken the award of there was no Saaho. Baahubali films and Mirchi gave him 3 huge hits and made him Pan India star too. But Saaho, Rebel are such big disasters that he will only get the title, if someone has to be chosen for sure.
Fans might not agree but 80's - Star of Decade was Chiranjeevi due to his consistency and 90's saw all 4 of the Big Telugu stars - Chiranjeevi, Nagarjuna, Balakrishna and Venkatesh consistently performing with few hiccups. 2000's saw rise of new stars and that decade could have belonged to young stars but no one had consistency and even in 2010's they did not show any as each one wants to be Rajnikanth and have a growing market every year with each film while the Industry just doesn't function like that!
