I deliberately stayed away from reviews and stuff and went in with an open mind, but I was so disappointed with the movie that I shed tears!!!! I thought it was awful, worse than OotP and that's saying something!
I mean, I know things have to be changed because a lot of what goes on in the books is in Harry's head and won't translate to screen well, and I know they can't fit everything in, but I think they made some really bad decisions in this one. Some of the changes were completely pointless. Little things, like the design of stuff not being how it's described in the book, doesn't bother me. But some of the other stuff was huge. Some of the questions that spring to mind are (I've done them in yellow to try and stop them being complete spoilers - they need highlighting to be read)
Apart from money, why cut out Dumbledore's visit to the Dursleys in favour of those awful scenes at the train station? They were beyond terrible.
I think they could have squeezed in the stuff about the Minister of Magic and his dealings with Harry if they'd wanted?
Why did Luna find Harry in the train and not Tonks? Not a big change, but why bother then?
If Ginny hid the book, where's the diadem that Harry has to find?
If Dumbledore never explained what he suspected the horcruxes to be, how is Harry supposed to start looking for them?
Why burn down the burrow? That really p*ssed me off for a million reasons...
Dumbledore's wand and its burial is integral to the rest of the story so why wasn't it buried with him? Although, rumours abound that the funeral may be in the next movie.
Are we ever going to meet Bill and Charlie Weasley? To me, this has been one of the worst omissions in the entire series.
Will there be a wedding at all, sincer Bill and Fleur never appeared?
What was the point of Fenrir Greyback? Neither he, not his background, were ever explained, so why bother.
Why was Neville a waiter at Slughorn's party?
Why did Dumbledore not put Harry under the bodybind curse? The whole point in the book was to stop Harry interfering with what had to happen, because Dumbledore knew Harry would try and stop it. How come, after 6 years of completely mistrusting Snape, we're suddenly expected to believe Harry would stay back because Snape told him. Plus the fact that Harry had oodles of time to stop Draco before Snape arrived and didn't.
Why didn't Ron speak or join Harry and Hermione at the end? It was out of character.
Where was the final battle? David Heyman said they didn't want the last scenes to be too similar to the ones in DH, but that doesn't make sense. Why would they be? It was a huge omission, anyway.
If anyone can give their answers/opinions to these questions, I'd be interested to read them. Although, if you think it's too soon to discuss it in case people haven't seen it yet, it's ok :)
