I just re-watched KOTCS this week, for the first time in a few years, and immediately after watching the first 3 films.
I didn't dislike it as much as I expected to, and there were a few scenes I actually enjoyed more than I remember. Everyone has focused so much on what is bad about the movie, let me focus on the things I enjoyed.
- In the beginning, Indy is grizzled, sour, and a bit lost. The loss of both Marcus and his father have really affected him, and in many ways he isn't the same Indy we knew, especially after the ending of Last Crusade. Once the action kicks in, and he meets Mutt at the diner, you start to see a glimmer of the old Indy, and when they finally reveal Marion, the real Indy really starts to come out. Look at Ford's acting in the scene where Marion comes out of the tent, the snake and the whole void collapse and reveal of Mutt being his son, and then the back of the Russian truck. Those scenes really show that the Indy we love is still there, he was just buried.
- Mutt, yes despite the obvious vine swinging debacle, is really a good fit for Indy. Shia takes a lot of grief for this movie, but his performance is not the problem. He's a greaser, with heart, and the scene of he and Indy in Oxley's cell really shows the chemistry between these two characters. It's a shame that the vine swinging will forever overshadow that character, because there really was a lot of potential.
- Karen Allen was really the heart of this movie, and her arrival is really the key scene of the whole movie. She brings Indy (and Ford's acting) out of the funk he is in, and the scene of her telling Indy that she has had a 'damn good life' without him is classic Indy/Marion chemistry from Raiders.
If I had to sum up each Indy movie with a one word description, it would be the following:
Raiders = perfect
Temple of Doom = fun
Last Crusade = heart
KOTCS = nostalgia
Is KOTCS the best Indy movie of the four, absolutely not. Is it the worst of the four, yes it is. But being the worst of the four Indiana Jones movies is still better than being the best National Treasure or the best Mummy movie.
