It is a great film, generally speaking, which represents a mainstream vision of Judas in common sense non-practicing and conservative Christian or secular mindset.
Perhaps, the image of Judas as a profound person who negotiated the conflicts and used to be in authority among the disciples of Jesus is heavily influenced by recently published translation of Gospel of Judas rather than traditional by canonical account.
Apart from the art implications of the Gospel of Judas there are certain extrabiblical accounts were being inserted. Although these novelties made a film plot very attractive; unfortunately it had being made on a theological inside"s count.
The whole concept of Judas who betrayed Jesus only because he wanted to force him exercise His supernatural power on Romans appeared to be dubious due to apparent contradiction with the Biblical account, provided another reason for that.
Luke 22:3 And Satan entered into Judas who was called Iscariot, belonging to the number of the twelve. 4 And he went away and discussed with the chief priests and officers how he might betray Him to them.
And also John 6:70 Jesus answered them, "Did I Myself not choose you, the twelve, and yet one of you is a devil?" 71 Now He meant Judas the son of Simon Iscariot, for he, one of the twelve, was going to betray Him.
The very reason why Satan entered into Judas we could find in John 12: 4 But Judas Iscariot, one of His disciples, who was intending to betray Him, said, 5 "Why was this perfume not sold for three hundred denarii and given to poor people?" 6 Now he said this, not because he was concerned about the poor, but because he was a thief, and as he had the money box, he used to pilfer what was put into it.
It looks like Biblical account represents Judas very differently from what we saw in the film and because Biblical representation of Judas is full and accurate this film could possibly draw the audience to the state of disorientation and confusion.
However, I would not judge the film author"s vision of Judas from the position of legitimacy.
Certainly, there vision of the most controversial disciple of Jesus has been put in life within a postmodernist context where a large variety of opinions always win against dogma.
