As others pointed out, it could have been better. The focus of this documentary was on the Southeast Asian ex Muslims in the UK and how those communities react and treat their atheists etc. Not bad, but could have been better, i.e. if they talked about the issue of apostasy in Islam in general, and the relationship between Muslims and ex Muslims in the UK and the rest of the Western world etc.
PS: It's funny to see how some of the members here, half of them females, are supportive of the way the young ladies in the film were harshly treated by their parents and communities for leaving Islam. It's mind-boggling when you realize that these Sspot female members live and do many things that are contrary to Islam in their respective Western countries. Lifestyles (from the music they listen to, how they dress and that they intermingle with men at work and unis etc) that could get them shunned and/or harmed by their beloved Muslim "brothers and sisters" in the Muslim world. As has been said before many times, hardly any of them wanna move to the predominantly Muslim countries and wish to enjoy the lives they have in the West. The hypocrisy is strong with these folks!
