Spoiler: Question about the last part of the movie
The movie was good, but there was a huge plot hole towards the end according to me. It may not really be a plot hole considering everything else that has happened till that point, but however I felt it was either the 3rd son was too foolish than all other of them (father and other 2 sons) or the story had a big plot hole.
Here is the point...
This is at the point when the 3rd son comes to know about his father and he wants to take his father to his castle.
Now the best thing to move a SINGLE OLD man would be by letting someone lie to the old man that they are going somewhere else and instead take him to the 3rd son's castle...the old man was anyways not in his senses and was fully dependent on others, so it would have been a really easy to somehow move him to whereever needed.
And the second son who had become king was anyways not aware of where his father was or didn't care where he lived or moved...so he wouldn't even care about if his father goes to the 3rd son or whatever.
This simple situation was over complicated by the 3rd son going with a full army to meet his father in the desert which was absolutely unnecessary and on top of that his father-in-law also got more army posted on the mountains, which led to all the foolishness that followed.
I would like to think that the 3rd son wanted to face the enemy and get his father with pride by fighting the war face to face and getting his father's kindom back or something like that, but it was clearly not the case as he sent the message to the kind that he is there with peace and only for this father, and also he did mention to one of his men that he does not wants to let the enemy know his father's location which means he really wanted to get his father out of there in secrecy or something....but if that was the case then you dont go out to do something secret with an army of men, that was to me pure foolishness.
Am I missing something here?
