This feels like a completely different movie without the clamour of schoolchildren and the mood evoking changes of outdoor scenery. It starts almost immediately with a uniquely orchestrated chase scene with a comical doppleganger decoy setup.
It seems that while every movie since the first has gotten progressively darker, this one comes out a good order of magnitude more brutal than any of the ones before it. There's also an emotional dreariness that goes on for almost too long before the director has interrupted it with something either more jovial or frightening.
I can only say that this movie provides an utterly different experience from the others despite this being something Yates has worked on before. I say he did an excellent job stringing the story together. The horcrux treasure hunt detective story mixed with a very realistic coming of age set of tropes gives the viewer a few neat surprises they haven't had the pleasure of seeing before.
