Like others commented - at a high level this movie follows the formula of the previous ones.
I do, however, expect decent/good acting if you get great acting/chemistry - that's icing on top. Going into the theater or before renting the movie - what were you expecting? Before you go and see a mummy movie that is an action/adventure, I do not think expecting a lot of great acting and academy-award winning chemistry is reasonable.
Scanning IMDb comments like I do, consider pausing with this one cause I'm gonna try to give you my view straight up.
