Let's put this "There's no Rachel Weisz" criticism to rest
While it's regrettable that Rachel Weisz opted out of this third film in the trilogy in order to be with her one year-old son, Maria Bello is a solid replacement and actually looks better in tight pants (as she's curvier and therefore more physically appealing).
Of course the film’s preposterous in the tradition of the previous two and the Indiana Jones flicks. But let's give credit where credit is due: “Tomb of the Dragon Emperor” bends over backwards to entertain with tombs, priceless artifacts, mummies, Shanghai, the Great Wall, the Himalayas, yetis, Shangri-La, zombies, a three-headed dragon and martial arts.
If you can get past the absence of Weisz and embrace Bello -- which, let’s face it, isn’t that hard to do -- this is easily the second best of the trilogy. Interestingly, Roger Ebert maintained that it was the best and he ain't no slouch when it comes to appraising pictures, whatever the genre (https://www.rogerebert.com/reviews/the-mummy-tomb-of-the-dragon-emperor-2008).
Yet my wife zeroed-in on the film’s flaw, which is the same as the previous flick: It tries too hard. It frantically throws in everything but the kitchen sink and is the lesser for it. (Yetis, seriously?)
