- The director of the film, Vijay Chandar, had release issues with his previous film Vaalu and couldn't bring big success after it finally released. So there is a doubt as to whether he will effectively handle a big star film like this.

- Thaanaa Serndha Koottam and Gulebhagavali, which will release along with Sketch are heist films, and so is Sketch. Thus, an obvious problem presents itself - comparison.

- Competiton from a biggie film like Thaanaa Serndha Koottam itself is tough, regardless of the sameness of genre.
