Indiana Jones and Mars Attack?

A newspaper's review of the movie reminded me to forget about logic as I watch this. With most of the recent films attempting to be as real as possible, even as they tackle out of the world concept, I must admit I almost forgot about movies that try to be just fun.
An Indiana Jones movie has always been about fun and going to watch the latest installment, Indiana Jones and the Kingdom of the Crystal Skull, I had hope to again capture the feeling and excitement I got from the earlier films.
The movie begins with the Russians forcing Indy to help them steal a mysterious item from a US military facility in Area 51. That location itself is enough to tell us the direction that this movie is heading. Indy escaped but without stopping the Russian from making away with the mysterious cargo. Then a young man appeared, asking Indy to help rescue his kidnaped mother and foster father and the real adventure begins.
As with Rocky Balboa, the film did not try to hide the fact that the main character has aged much since the last outing but age hasn't slowed Indy down much though. Except for the occasion whining about how things used to be easier, he still made some unbelievable escape. He isn't any clumsier than he used to be but if he can take on a younger Russian commander, I guess he is still pretty strong.
Unfortunately, despite all their attempt, I just don't feel like this is an Indiana Jones movie. The chase scene in the jungle is the only entertaining part of the movie but I keeps thinking Pirates of the Carribean as I watched that. Don't know why. Some peole may think the man-eating ants are a bit far-fetched but I thought it was totally cool. Hey, it's an Indiana Jones movie. I will never forget the 'monk' in Temple of Doom who can retrieve a man's beating heart right from his chest.
Well, that was about it. The rest of the movie was rather dull for this franchise. Even the famous theme music is very much toned down. And after 19 years of choosing the right script, they can't even get that right. I don't expect the script to be flawless but there is just too many missing ingredients. I am all for exaggeration but certain recipes just doesn't mixed right. You will understand what I mean after you seen the film.
It's not a bad movie, but it is a lousy Indiana Jones movie.
