I've discussed with a lot of friends that didn't like the movie as much as they would have loved to because to them, there was no plot to enjoy. Just small snippets of subplots here and there, and too many to keep up or understand. I have to say I quite enjoyed the way the movie tell its story, because there is one, but only if you can grasp the winks and universe building this one has to offer. I guess you can't really enjoy this as a one shot, just going to the theater and expect an amazing experience if you don't keep in mind that what happens here are the many causes of what we already know watching the Potter movies (and even more, reading the books). Some people say Rowling gets her facts mixed up, I'd say she's incredibly accurate, as much as you give he the credit she deserve, which is she knows what she's doing. If you believe that to be true, you can grasp the many clues that will tie this saga the the next and, oh boy, that's so much to get in one sitting ! Also, don't miss the chance to see it in theaters. Yates is again a master at his craft and gives us so many incredible shots and sequences. Yes, There ARE action sequences even if they aren't as numerous as one would think. I have to confess, the first one looked a bit messy but it describes a messy situation, so I guess it fits. But it's more a character movie than it is a stand alone. I'd say it compares to the Empire strikes back, in that it doesn't tell as much as it builds drama and gravitas. I won't spoil it, but Keep in mind what you see, compare it with what you already know is gonna happen and just think of what could happen to get from there to there. If your imagination is not rusty, you will get it : Vertigo.
