As for the acting, I would say before watching this movie that Harrison Ford still has it in him like that wrestling chant "You still got it" when some wrestler returns to the ring after a long hiatus. Yeah Ford still has it after watching it, but all those action scenes are not designed for him specifically, so they had to CG it out as well as having stunt doubles. The dialogue seems mostly cheesy with Ford saying many variations of "This is not good" every time something bad happens. As for the supporting cast, I'm starting to hate Shia LeBouf even more if they continues to hog big summer movies that started with Transformers. I don't know if he was the perfect choice to be Indy's son, but he did okay I guess. Kate Blanchett as the antagonist seems weird at first and didn't really play one since she always had her goons ready. Even Mary's positive attitude during the action and near-death scenes is really awkward. Plus, how many times can Indy's long-time partner double-cross him in one movie?
Lastly, I like to rant about John Williams's score for the film. I know that theme song is very symbolic with the franchise, but it was way overplayed in many variations throughout the movie. Then again, that theme song is probably the only good song for the whole franchise compared to the many symbolic hits in the Star Wars flicks he made.
If I would score this, it would be a 7/10 at best. Steven Spilberg did some things right and wrong with this long-awaited flick. At least Indiana Jones is relevant again for people who appreciated it back in its day, but it is likely for the last time. I don't see any opportunity for the franchise to continue with Ford continuing to be Jones, but crazier things have happened in the movie industry.
