Sony max is a channel which is a movie specific channel and is a part of the Sony entertainment television. But in my opinion this channel is not enough worthy to be watched.
And the reason is that it generally show those movies which are not popular or either we don’t know about those movies. They keep repeating some specific movies like "Suryavansham", "Don no. 1" etc. which irritates the audience. So it does not seems to be a dynamic channel which shows different and popular movies and that’s why it should be avoided. For now it can be watched at night because IPL is currently running on this channel otherwise it’s very boring.
