That twist though at the end, it was unexpected.
*SPOILER ALERT*
On the first part of the movie, when he found the little girl, first thing I thought was maybe it was the girl the mother was looking for in the beginning of the film but then came the name Iris which changed what I expected.
The part of Sully being his daughter was pretty much expected from the start but her being the little girl at the end shocked me. I tried watching it again trying to look for clues or something that I might have missed but I found none. It was a good thriller, a little bit of romance but a with a great drama and story-telling. George Clooney's acting was convincing and so does the rest of the cast and I hope Mr. Clooney's gonna come up with more films as great as this.
