The Ramzan fasting effec is showing up on the CBO. Add to that Varalakshmi Vratham last Friday (August 20), which kept the family audiences away from the theatres. This resulted in Karthiís Naan Mahaan Alla taking only an average opening. However, the film opened at the number one position and carries positive reviews. At number two is Prakash Raj produced Inidhu Inidhu, which has failed to take an opening. In the third place is Vamsam, which is ok while Madhrasapattinam is rock steady at number four, and Expendables is at number five.
