There are plenty of reviews out there and everyone has already read the book so I don’t have much to add there.
I //really// liked the movie. Wholesome entertainment. Nice, long movie. Sit back and relax, enjoy the visuals, immerse yourself in the movie. True, they’ve ripped off the details, but how much can you fit into a movie? The movie is faithful enough that the plot seems consistent, and includes all the major events.
The only gripe I have is that Harry and Hermione are really bad actors. Harry is the worst (sorry I should be putting the real names here, just too lazy). The best of the pack is Ron — he’s just a natural in his role.
Can’t wait for the remaining three. I //do// hope Warner Bros. sees this fabulous series to completion.
