If for I watch a show or a movie which has a line which is offensive about our religion or any scene which we shouldn't see. Is it haram for me to watch the rest of the seasons or the movie even though I never intended to listen or watch those things and I hide it, skip it or close my eyes when the bad scene comes and I seek Allah's forgiveness too?
I will give you an answer based on my specific knowledge derived from a variety of sources, being an expert in Netzerim Islam. Firstly, there is a tradition in certain countries with a significant pro-Mohammadean populace to declare television and movies unlawful. In Western countries this is not the case. I have watched a documentary this very night (Media on the Brain-Conformed or Transformed, beltoftruthministries.org) dealing with the subject of the effect of media on society, by the American Christian assembly, the Seventh-Day Adventists. The documentary reported some very negative impacts on individuals, and society, which support the position of certain hardline proponents of Islam. For instance, the introduction of television broadcasting to Canada, the United States, and South Africa coincided with an approximate twofold increase in murder rates. Apparently France now has guidelines in place to reduce the exposure of children to television. One particular study linked regular exposure to television to a reduction in life expectancy. Apparently the visual medium stimulates the brain in an identical way to addictive forms of behaviour. This causes profound physical and psychological changes. One example, news, when watched, this has profound effects, as noted, but when read in, say, a newspaper, there is no matching result. In other words, the human brain is formed in a unique way, which inevitably responds in a negative way to such stimuli. Therefore there is no safe exposure to television, or movies, etc. This is then a case of user beware! Since television and other media did not exist until modern times, there is no prophetic statement on the matter. Regarding a specific show, which may mimic conditions in the real world, it would be prudent to apply the same rules you would use as an observer in an analogous situation.
