The thing is I am actually quite conflicted.
The Deathly Hallows Part 2 contains a bunch of greatly done scenes:
action packed escapes, mere character behaviour that makes one laugh, appealing flashback sequences, neat animation and gloom.
Unfortunately the overall impression is very underwhelming.
The worst thing is that the film is incredibly rushed, already when showing the opening credits it seems.
Important scenes lose their effect because of their shortness or speed-up.
(for example: the death scenes were emotional, but too short for people who deserve much more attention)
The whole story of Dumbledore is totally left alone even though it's one of the most important aspects of the 7th book. And that is not the only neccessary detail that was just ignored but since they failed to tell the story understandably in Part I already it's no surprise.
Snape's story lost its touch and believability because the director refrained from working towards it before.
It's just a big mess, I wonder how people who didn't read the book understand the plot?
My second main point of criticism is the drama in the film.
Sure, it's the final part of the franchise it needs to be epic and all.
It just doesn't work all that well when the minor scenes get all the melodramatic music and acting and cease to support the actual moments that matter.
(e.g. the fight lacked any characteristics of one. There was just a building collapsing and the fight against Voldemort went by so fast it seems almost unreal.)
It didn't help that there were many pointless ore ridiculous moments and that the continuity was questionable.
Furthermore did characters beside Harry and Voldemort get very little attention.
Ralph Fiennes did well, Daniel Radcliff's so-so acting is nothing new anyways.
But seriously, the others are equally important!

Also I already feared the epilogue which was already disappointing in the actual book so yeah, in the film it was even worse as many things were just left out.
Well, it just makes me very sad that David Yates ends this gigantic franchise, that started out so well before he began to direct, so passionless. The last scene (excluding the epilogue which isn't much of a better ending) is a joke.
The whole film seemed to be put together so unenthusiasticly.
That's not what I expect of a finale.
This opinion comes from a person who loves all the books and has given up on the films since the 5th part. So, people who did not read J.K. Rowling's book might be very pleased with this film. People like me might share the opinion.
The readers are always comparing, they just can't help it. ;)
