Not that the Rock is not a good actor. This guy has impressive screen presence. I feel that the movie producers did not take advantage of him as much as they could. The plot was non-existent. Why should we care about what happens to Memnon at Gommorah thousands of years before the Pyramids. BTW in the "Mummy returns" movie it is evident that the SK lives in the post-pyramid period of Egyptian history (?). Also the Arkadians is the name of a Greek (?) tribe.
