I wouldn't say I didn't enjoy it, but I thought it could have been done better. I think it would have been easy enough for them to not include the parts that didn't happen in the book but instead actually include some of the more major parts of the book. Some conversations that are quite essential to the plot of book 7 just weren't there in the film, which is rather dissapointing but oh well.
The main issue I had with the film was due to the cinematography, I felt that a lot of the time the camera work wasn't the greatest and the scenes just didn't look as nice as in the others.
I also felt like the colour palette was awful, it all seemed like all the shots had been greyed out. I understand it's to represent the darkening times in the story's universe, but surely that could have been convayed in detailed, convincing character performance.
I definatley felt like a lot of the acting was very poor. It's almost as if almost every scene was done in one take and no-one had the balls to say "(Actor) I don't think that was as good as it could have been, let's try it again" Some scenes were well done and gave the desired effect such as humour, but others (Dumbledores scenes in particular) lacked the force that they gave in the book.
All being said however, I wouldn't say it is a bad film, I just think it could have been made a lot better with very little change.
