DaasYochid- Rav Ovadia tz”l writes that you have to close your eyes bec. of hirhurim, not bec. of erva. That is why I said “technically”.
Also, when I asked you what my false assumptions were, I want to know if you disagree with my svara, not whether one can be mosiach daas. Also, as I said before, I belive some poskim hold “Al Tifnu” is only for idolatry. (Shulchan Aruch 307:16, Beur Halacha there) Furthermore, there is no Yeharag Al Yaavor by watching a movie bec. it is not erva and therefore there is no ?? ?????. Therefore, now it depends if you agree with my svara whether or not we need the Gemara of Darka Achrina or not. If we do, then maybe Darka Achrina is only by parnassah purposes and the like, not entertainment. But, maybe it is also for entertainment. It also obviously, would depend whether one has hirhurim. {Even Lev Darka Achrina doesn’t help if one will have hirhurim, bec. it is only when one can trust himself he won’t have hirhur}
