"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.
