Kannada star Upendra's dystopian sci-fi film 'UI' has raked in ₹13.45 crore in just two days across India, with ₹6.50 crore collected on its second day. The film's opening day saw a strong ₹6.95 crore, primarily from Karnataka. 'UI' also saw moderate success in Telugu regions. The film boasts high occupancy rates, particularly in Kannada-speaking areas. While praised by Bollywood's Aamir Khan, an ETimes review criticized the film's preachy narrative, describing it as more of a lecture than a cinematic experience, despite raising valid points about the socio-political climate.
