The movie was kinda dark, as in the screen was actually quite difficult to look at. Most of the scenes were night time or in underground settings, and when they weren't the screen was fantastically bright. Apart from yhat I see no reason why it failed.

The sequel had Johnny Depp lined up as the Invisible Man, and who wouldn't want to see that inevitable team up between "evil incarnate" and Mr. Hyde? The Mummy was an origin story, as Mr. Glass would say. Its too bad we'll never see the rest of it.

He already had the Mission Impossible franchise as well as the Jack Reacher series (well only two films). It just seems so odd that he'd suddenly wanna headline a horror cinematic universe and especially one such as The Mummy. It could arguably be the worst film he's ever starred in, A truly odd misstep from such a reliable star.
