To understand why "Moviesda" is inferior, you must first understand what Vishwaroopam actually is. Directed, written, produced, and starring Kamal Haasan, this film was India’s first "spy-thriller" made on a pan-Asian scale.
I'm assuming you're looking for a comparison piece on the movie "Vishwaroopam" (2013) directed by A.R. Rahman and "Vishwaroopam 2" (2018) also directed by A.R. Rahman.
During this time, Wisam falls in love with a woman named (Andrea Jeremiah), a fellow agent.
