Hey, sequels rarely overpower the first movie, and of course, this one failed to overpower the first movie. But, it wasn't as bad as some other sequels, seeing as I didn't regret watching it, other then better camera working, slightly more interesting creatures, and a bit of comedy, it doesn't really do a good job of succeeding...
Albeit, it did have me interested at certain parts, but some of the parts just left you right out there, snoring. If you can ignore the boring parts and wait for interesting things to happen, then this movie will probably be higher rated for you, I recommend this to any mummy fans though, as mummies are always interesting to mummy fans(Strange, you'd think mummy fans were more of the dog type...)
Anyways, 6/10, if they kept it interesting the whole movie it would have been 8/10 though
