O2

First 30 minutes of the movie was very good and setting the context well for what's coming up next. Rest of the movie was simply dragging and easily predictable, length of the movie could have been reduced by 30 mins to make it crisp.

Acting of Nayanthara was pretty normal and there's nothing great to mention.

Inspite of the negatives mentioned, one message which can be taken away is - How might we strive for oxygen in future, if we continue to spoil the nature the way we have been doing?

The story and screenplay of this film are abysmally written, lacking creativity and depth.

Despite their efforts, all the actors fall short of delivering a compelling performance.

Nayan's decline is evident with each film, as her skills seem to be diminishing.

The director's incompetence is glaringly obvious, resulting in a major failure.

The visual effects used in the film appear cheap and poorly executed.

Overall, this film is simply not worth your time, failing to offer any redeeming qualities or engaging moments.

Good movie not bad

Finally watched this movie , experience was superb and heart touching. Theatre release would have been better.

Good and nice to seeing this film.

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.

May be it is predictable or done with references but a different experience and a good film. Technical work of the film is also well done like cinematography, editing and sounds. More than worth for OTT release.
