_Elvira's Haunted Hills_ is a horror comedy; To be precise, it's a parody of Hammer horror, in particular, those based on Edgar Allen Poe works. The good news is: if you are unfamiliar with Hammer or Poe, you'll still understand what's going on.
The humor here is what one would expect from an Elvira movie: cheesy and self aware - hell, there are even fourth-wall breaks! There is also plenty of cleavage, but sadly, no nudity. Can't blow that PG-13.
Not really too much to say about this one. You're either on board right away or you're not. On a technical level, it's all great: the movie is leaning into its low-budget charm, so it's a feature, and not a bug.
Probably does without saying, but this is a must watch for any Elvira fan. In fact, I like it more than _Mistress of the Dark_.
