I saw it yesterday.
It is exactly what you expect for an Indiana Jones film.
Disappointing in respect of it's not moved anything along, nor does it push any boundaries etc. However, it does fit in with the other Indy films.
What I found most disappointing though was at the end, the very clear symbology of the hat at Mutt's feet. It seems overtly commercial to so blatently open the franchise up for two or three more films that way.
As a side note, prior to the film was the trailer for Kung Fu Panda, which looks like it should be very enjoyable.
