O2

I don't have any idea if this kind of survival movie is ever made in India. Or maybe, I'm just came across this for the first time. The movie is okay because it isn't entirely a new concept. Some concepts are taken from Foreign movies too. Besides,the movie is predictable. Moreover,the child breathing problem disease makes this movie bit unrealistic like seriously, putting something for making this movie more intense.

When the Oxygen (O2) level will be down, everyone will look for the ways to survive and for that they will attack, even kill one another. In this way, everyone will try to hunt this boy down for attaining his oxygen cylinder. It is more like a survive journey of a mother to save her son vs people on the bus in stead survival of a landslide.

But,the rest is okay. One might feel bored because of it's duration. But, if it is solely based on survival, it will be more thrilling and exciting. Sadly,melodramatic mother and son concept ruined it.
