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.
Hype Backlash: Believe it or not the film actually did get quite a bit of hype in the UK prior to its release — in part because of the popularity of Corden and Horne, and also because of the number of people who thought "hey, with a title like that, it's got to be good, right?" — leading to it taking quite the critical drubbing when it didn't live up to expectations.
Inferred Holocaust: Every female child has been turned into a vampire on their eighteenth birthday for a thousand years, do a bit of quick math and that means there were a lot of women who were turned or slain (probably by their own families...).
How about the fact that there wasn't a single positive male character in the entire movie? Fletch was an immature, cowardly pervert and Jimmy was a whiny doormat. Paul Mc Gann's character was the closest thing to a positive male character and he was pushing it, as a vicar who swore heavily. Let's not forget the all-male group of villagers who sent the boys and girls to be sacrificed either. Do any of these men come off well compared to Action Girl Lotte?
Jimmy has some positive elements (he's not a Jerk Ass and is at least somewhat mature, unlike Fletch), however he spends most of the movie bewildered by what' going on around him. Fletch on the other hand is a bit of a cowardly Jerk Ass who, complaining all the way, is at least able to deal with the situation at hand.
