I completely disagree that this movie was boring or crap. This was the best movie I've seen in years. To each his own.
I picked up a copy of the 3D blu-ray yesterday and watched it for the first time. Going in, I had no clue about the story at all. This was a good thing. I would categorize this movie is an adventure suspense movie, with a lot of history.
The movie gets you to really think, and to imagine being inside the maze of clockworks. If you're looking for a thrill-a-minute action movie, with car chases and helicopters blowing up, this is not it. If you're looking for a trip into the early 1900s Paris, France, with a sense of wonderment, this is a great movie. It's interesting to see how culture was back when movies were just beginning. The movie takes several twists and turns as well. You think the movie is headed in one direction, and then it changes. You're also yelling at the characters, like - tell this person such and such and they'll understand you better. That type of thing. And the story goes back and forth in time, very confusing unless you're watching intently. This is not a movie to watch casually while you talk with others in the room about different things.
I'm looking forward to seeing this movie again this weekend, now that I know the twists and turns, to see all the things I missed.
The 3D is very well done. No cross-talk like others have said in my setup (a passive LG set). I really enjoyed the 3D movement through the train station, swooping through all the people, going through the clockworks. 3D really enhanced this movie for me. (Note: I understand 3D problems - Drive Angry and Rio were both unwatchable and distracting to me due to cross-talk problems, but I upgraded my blu-ray firmware, and the cross-talk went away. Drive Angry became a very enjoyable movie from an unwatchable movie).
It's a movie you need to take time with and enjoy. It's not for young kids, even though the main characters are a mix between young kids and older adults. I enjoy mindless movies like Die Hard as well, but don't treat this movie as something like that. Sit down and take time with it, enjoy the wonderful scenery, the history (read about what's true and what's not about the historical characters afterwards) and just enjoy the story, the cinematography, and if you have a love for old films, this movie is perfect.
Don't read any summaries of the movie before hand, it will spoil the suspense.
