Filmmaker Onir has criticized Karan Johar after he posted a cryptic tweet over the clash of his production 'Yodha' with the upcoming Katrina Kaif and Vijay Sethupathi starrer 'Merry Christmas'. Onir mentioned in a tweet that small budget indie films cannot survive without good shows, but big Bollywood releases complain when there's another big budget release, even though they talk about caring for each other in the industry.
