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?

RATED 6/10 Language: Tamil Source: Hotstar

Opt title for this survival thriller. The story is simple and predictable, still they made it watchable by adding some good characters in the flow. If they trim the movie with some unwanted scenes in the first half, it could be more racier and entertaining one

There is some cliche sequences between mother and son. It looks like they added to boast Nayanthara role. The movie is definitely suitable for OTT release only.

One time watchable as this is the first attempt on survival theme in Tamil cinema.

--repeating again for 600 characters limit One time watchable as this is the first attempt on survival theme in Tamil cinema.

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.

Different level.

Dint look like tunnel or sink hole some reviewers claimed. I have watched both the tunnel and sink hole. Other than survival part this one is total different which has an element called oxygen. Give it a try definitely worth your time.

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.
