I have not seen it yet, but based on what I am reading here, I do not have high expectations for it.
One of my biggest concerns is that - I cannot stand Shia. I don't think he is talented at all and he drives me nuts in every movie I have seen him in. And to hear that he is playing the role of Indy's son and is expected to take over the franchise makes me sick to my stomach. This ruins it for me.
