The movie in short doesn't lack anything as such but the timing seems to be off, as after Scam 1992 which truly stole hearts and gave an in detail / insights on life of Harshad Mehta , this just feels like a trailer or sumup of the tv series!
Abhishek bachan has done a spectacular job at acting, he is so suited for these loop hole exploiting gujju roles!
You though certainly can't compare it with Guru, as guru was next level but this movie is a good watch !
But yet if you watching it for detailed insights of Harshad Mehta story, Scam 1992 would be a better pick!
