Brother I have seen arrivals three times. but there is a hadith in which Holy Prophet (SA) have described the Physical appearance of Dajjal.. He said that he is a Jewish man , powerfully built and have curly hairs... So Undoubtedly he is a person....
If it is stated in these movies that Dajjal is a system , then I really don't believe them because there is the hadith that proves it otherwise.. And Hadith is more important for us then any self made interpretation...
Undoubtedly I agree with you that the whole system of this world is the System of Dajjal but it is not Dajjal itself.. All that you , I and the rest of the world is seeing today is the preparation by Israel for the arrival of their False Messiah i.e Dajjal, which is expected to come really sooner then we expect....
Moreover Holy Prophet (SA) have told us the location where Hazrat Isa (AS) will kill Dajjal while Dajjal will be runnig to save himself... I don't remember the name of that area but today its in Israeli territory.. And Guess what is built on that area today???????
Israelis have built an AIRPORT on that area ... It is clearly evident that he will try to run most probably through a plane but will be unsuccessful.. so all these hadith proves that he is a man...
