I found this movie funny all the way through. All though the movie has lots of adult sex humor along the lines of Austin Powers but more of it, I would caution taking any kids. I saw a few 8 to 10 year old children with parents in the movie when I saw it.
I like Adam Sandler movies so for me it was funny. Left me laughing well after the movie. But for some of my friends who went with me, they were completely unimpessed with the comedy in the movie even though they thought parts were funny. That is why I say this movie is not for everyone in the title.
The movie was very long overdue and I think was a very good movie to watch. Whlie it was a little bit more far fetched from the prior Indiana Jones movies but the story was good.
It also sets up a nice transition to future movies with Shia LaBeaouf.
