I don't know how they did it, but India managed to make a movie with modern special effects that somehow look as ancient and old fashioned as the old Godzilla movies. It's so awful it's funny.
Hey India, there's this thing called physics. You might want to read up on it. I once took an online physics test which said I scored lower than the average monkey would, but even I know that things in motion don't suddenly stop.
And just because a bunch of robots take the shape of some familiar object doesn't mean that shape will make the same sounds or work in the same way as the object (snake, large humanoid, drill bit, etc.).
