These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Older Than They Think: The ending is more or less exactly the same as Tanz Der Vampire- heroine turns into a vampire in the final scene and turns the hero, and while they run off together, another character's efforts to contain and destroy vampirism instead allows them to spread and take over the world. This is particularly hilarious when you consider that the actor and actress playing Alfred and Sarah on the Vienna revival cast recording of Tanz met while playing Romeo and Juliet in the musical version.
