Yup, Karan and Upsana are really boring and bland. Upsana tries to stick to her script she is given but Karan gives no bhaav. So I can't really blame Upsana, the woman tries to stick to whatever she is given but neither Karan nor Sonakshi respond to it. It is important for hosts to show some charisma or enthusiasm to whatever they are hosting but Karan just doesn't show either of those things. Wahi and Gautam were so good, they actually played around and goofed off so much. They were themselves and didn't just follow a script. Rithvik and Karan Patel were good too, I always loved Rithvik as a host but since both Rithvik and Karan Patel were good friends, their hosting came kinda natural. I have never seen Karan Tacker host before nach baliye but in the first episode it was just him following a script and not much interaction with the contestants or judges. With Upsana it has become worse since neither she nor Tacker connected together as hosts.
