There are many things to be critical of in this episode; the plot is nonsensical, the dialogue is preposterous and the acting is hammy. And yet, to quote Roger Ebert's review of The Mummy, "I was not bored, and sometimes I was unreasonably pleased." I had a lot of fun switching off the critical part of my brain and getting swept up in the pantomime drama of it all. I cheered when the day was saved by love and I gasped at the impending heartbreak foreshadowed by Charley and the Doctor's final exchange. A good fun way to spend a couple of hours.
