The humor in "The Mummy: Tomb of the Dragon Emperor" is the worst of the series, but overall, I think this third "Mummy" movie is slightly better than the previous film.
They get away from Imhotep, which is a good move. He proved last time that maybe one movie was good enough for him. Also, there's nothing in "Dragon Emperor" that's quite as stupid as the third-act appearance of the Scorpion King--oh, wait, no, that's not true. There's the part where one yeti tosses away a bad guy, then glances at another yeti, who makes a goalpost signal with its arms. But at least the yeti bit is mere seconds, while the Scorpion King . . . blah blah blah.
The snowy scenery is fun to look at, and there's less in-your-face, outrageously unreal-looking CGI. Downside, though: what did they do to Mrs. O'Connell? She's not only not played by Rachel Weisz, she isn't even the same character. Booooo.
