    Finally watched O2 after curiously waiting since we saw the trailer - and it was a mind blowing goosebumps movie, probably first of its kind in Kannada! Different bold story and genre is unique and worth embracing and encouraging - just as Appu and Ashwini have done to produce this movie from PRK. You forget the actors and connect with all the characters completely - especially dr Shradha and Osho played by Ashika and Ragav Highlight of movie and its effect on you is the BGM, pleasing voice in songs and mesmerising music by Vivaan, Ninagagi touches your heart and Nashe seeps into your very soul and stays with you for long! Location and cinematography is simply stunning and teleports you to the beach, lighthouse and labs. Cultural context weaved into story is clever and works effortlessly, giving a seamless switch from lab science story in one place to old school meen curry romance in Mangaluru. Medical & research setting is very detailed and accurate, will inspire young minds with its message of striving to do what's not been done before. Must watch in theatres movie for its overall experience of all elements of past, present and possible future coming together in right crisp proportion & executed excellently by debut Directors Prashanth Raj and Raghav Nayak! Big applause to O2 team for Kannada content on par with any other industry in India and the world!!!!

    Watched today in theatre. Very good script, direction, acting. Songs could have been avoided. It keeps you engaged till the end. Ashika is brilliant throughout the movie. I have never seen her talent in earlier movies. Praveen should have essayed her lover boy role. PRK production always look for fresh talent, fresh ideas and not into too commercial aspects. Ending could have done in different style. Dr Mrityunjay role in the end revealing the suspene was very meek. I thought Dr Mrityunjay is a spoiler for not letting Ashika to succeed in her research. Her assistants alsoessayed memorable role.

    First of all, I just watched the trailer of this movie and it felt like it would be a good watch but this movie believe me is more than that. What a story hatsoff to the director, writer and the actors. Both the male actors who played the role of Osho and Dev were amazing in their performances. A perfect romantic thriller I have seen after Sita Ramam. We expect more such movies from our Kannada cinema. Everything was perfect in this, the movie was not stretched a lot perfect suspense built and the romance shown in between. Osha named Shraddha as Emergency and this movie is just completely brilliant. Must watch for everyone.

    "O2" emerges as a breath of fresh air in the Kannada film industry, blending medical science with spiritual elements. Ashika Ranganath and Raghav Nayak delivers a stellar performance, portraying a doctor's quest to revive the dead with a groundbreaking drug. The film's unique premise and emotional depth, endorsed by the late Puneeth Rajkumar's production house, make it a must-watch. Despite minor flaws, "O2" is a commendable experiment that keeps the audience engaged and offers a heartfelt cinematic experience. Brilliance of director is clearly visible. Over all I will rate O2 movie as 10 on 10.

    Sci fi movie which shows if there's a desire to achieve something, humans have a incredible will power and never stop until it's achieved. In the journey to achieve they're ready to forgo the things they love sacrifice comforts and do anything and everything until they reach the destination. Kudos to Raghavendra for engaging screenplay which keeps the viewers hooked and not to forget his acting skills. He slips into the character and is at ease, looks natural on screen. Ashika Ranganath portrays a person on a mission to accomplish something and does it well. At some places she reveals the human side to desire some comforts but when the thoughts of accomplishment takes over she quickly changes her priorities. Praveen Tej is brilliantly manges his roles and gives a spotless performance . The main characters are well supported by Punith and Praveen Belavadi does his usual job of being a bad sadistic guy but in the end he's awed by the truth and accepts it. A must watch movie for all those content oriented people who love pure story based movies.

    The movie was a brilliant masterpiece crafted by the dynamic duo of directors, Prashanth and Raghav. From the breathtaking background score to the captivating screenplay, every aspect of the film was truly impressive. What struck me the most was how they managed to simplify the complexities of a science-themed movie, making it accessible and engaging for all audiences. Hats off to the director duo for their innovative approach and stellar execution. Big shout-out to the producer Ashwini Puneeth Rajkumar for supporting such bold and experimental cinema. Only PRK has the ability to take a bold call and choose content over commercial formula movies!
