I don't want to spoile the movie so I won't go into the details of the story but it's a good sequel with no changes in the details of the first movie to fit the second. In short words, it's a wild ride.
After I watched the movie I knew I focused on 2 things, first the geographical mistakes. If you're not from Egypt then you wouldn't notice that the Pyramids of GIZA are no where near Sinai and the Karnak Temple of Luxor is in Egypt not in Jordan. I have been to both and I assure you that they don't appear on the map near the Aqaba bay. That's a major mistake of the director.The other thing was Megan Fox :D. Enough Said!
