I don’t think anything I write will have any bearing on whether or not people go watch Harry Potter and the Deathly Hallows. If it’s your thing and you’ve watched the other movies, you’re going to watch the final installment. If it’s not your thing, you probably aren’t going to go, even if I say it’s the best of the bunch. Which, alas, I’m not going to say.
The Deathly Hallows was enjoyable and it wrapped up the series, but it was rather anti-climatic. I’ve talked to a few people (die-hard fans and moderate fans) and they said the same thing.
For one thing, some previously important characters are only viewed for a few seconds in passing. And there wasn’t enough Alan Rickman for my taste!
Another thing that I found a little strange was how different the soundtrack was from the previous ones. The main theme was the same, but it was barely used. In fact, there was at least one time when I thought they were trying to imitate some moments from Lord of the Rings (not too successfully, I might add). It was a bit of a surreal experience. I certainly don’t regret watching it, but it’s not going on my list of movies to re-watch.
