Bad mainstream flick aims at money and lacks... everything.
"The Mummy" was not something great, but at least it was funny. Then "The Mummy Returns" followed and was also funny. Then they decided to make a prequel/spinoff from TMR. The movie is boring, thinking it is original and epic, but fails at everything.
The Rock acts like he is a robot, the effects are pretty average, the plot is somewhat familiar, the script features no memorable quotes and it is just a bad movie.
That is all i can say. But at least it is better than "Scorpion King 2" which was literally the worst movie i have ever seen. But still, this is just bad.
The violence in this movie is not that strong. You briefly see a decapitated head, of which i think, that children under the age of 12 will not handle. But it is not a bloody movie or something.
