I found this enjoyable for what it is. I think much like Dracula this feels kind of shallow, but again, there have been a few iterations on The Mummy since.
I liked the costumes and makeup, especially that of the mummy. The mummy’s look maintains a line of continuity from when the bandages were fresh, then aged, then soiled, until eventually there are bullet holes and battle damage! Very cool.
I found that I sympathized with Kharis/The Mummy the most. His actions were driven by love whereas the other characters were driven by financial gain or revenge. It’s a shame he couldn’t live with his beloved priestess forever - but we also don’t know how she feels about him.
If there are sequels from Hammer I will certainly give them a try.
