- In the beginning scenes with Ardeth and the Medjai, there are like hundreds of Medjai. But once Ardeth and Dr. Bey confront Rick, Evelyn, and Jonathan about awaking Imhotep, all the other Medjai disappear, off doing who-knows-what. It should would've been useful to have even a dozen scimitar- and rifle-wielding warriors helping out. (At least in The Mummy Returns, they mentioned the other Medjai had to get ready to fight the Army of Anubis.)
- After Imhotep has "absorbed" three of the Americans, leaving only Mr. Daniels, the party is driving in car to get away from Imhotep's zombies. They know they need to protect Mr. Daniels to prevent Imhotep from getting fully regenerated (another case when more Medjai would have been nice). So why do they leave him unprotected at the back of the car? Dumb.
- And then after the zombies pull Mr. Daniels off of the car, the party keeps driving on, knowing full well that they are letting Imhotep get fully regenerated. Sure, there were plenty of zombies, but Ardeth, Rick, and Dr. Bey were all pretty badass fighters. You'd think they could've held off the zombies while Mr. Daniels got back in the car.
But this whole blog post is a waste of bytes. It just bugs me every time, probably because I enjoy the movie so much.
