This is supposed to be the darker Harry Potter. It’s not really dark, and that’s because the series is hampered by its juvenile beginnings and main audience. There is a little blood and killing, but nothing too sinister. It’s part 1 of a two parter series finale, and that does allow them to avoid a happy ending (much like The Empire Strikes Back) as Harry and friends continue the fight against he who must not be named (Lord Voldemort).
The films, like the books, suffer from too many characters and no flow in the story. There are fewer characters in this film, which should simplify matters, but there is still no pace or rhythm. There is potential to create a sense of despair or suspense when Harry, Hermione, and Ron are on the run in some impressively desolate locations, but it doesn’t happen. The film jumps from drama to action to comedy to boredom with no cadence. A wedding is thrown in for no apparent reason, as are people flushing themselves down toilets. The film is a mess and increasingly tedious as it progresses. At least young males have Emma Watson for eye candy. I’m not sure who young women have to ogle in the film. Robbie Coltrane? Alan Rickman? Bill Nighy?
