It wasn't really bad as a movie, it just wasn't, in my opinion, as good as the other five.  And it changed more stuff from the book than any of the other five.  That said, the local movie reviewer loved it . . . something about "it was significantly longer than Transformers 2, but felt like it was shorter" and "best of the HP movies so far".  To each his/her own.   :-)<br/><br/>A couple good examples of bizarre changes that shouldn't spoil anything for those who haven't seen it: the invisibility cloak was a non-entity in the movie aside from the train scene at the beginning and they added a strange scene at the Weasley's over Christmas that didn't really seem to serve a purpose.  On the other hand, they did decide to show Draco working on the vanishing cabinet, which was a good move for a film version, I think, and did change a few scenes to add Harry and Hermione discussing relationships (probably good, since they basically vocalized things that we only get from Harry's thoughts in the book).<br/><br/>We'll probably pick up the extended ed. DVD to complete the set and to see what scenes/info the director adds back in.
