Thought it was terrible, Jones was written, and directed to be just a hollow shell of the hero he once was, with no real Redemption to his character at the end.
I thought Crystal Skull was more than a little ridiculous at certain parts, but I would have been happy seeing Shia Lebeouf continue in his role as Indy's son, and see that relationship dynamic play out, however they completely wrote his character off, and then tried to fill the "holes" of his absence. Overall, after watching this I pray that if they try to make another Indiana Jones movie, that it's taken out of Hollywood's hands and put into the hands of someone who actually cares about the characters.
