I think this is why people think it sucked
I saw it without knowing anything about it. Just checking out the trailer, I can see why people are shocked by the bad ratings. It does look like a great wuxia epic with all the drama and eye candy you could want.
When I go to watch a kung fu film, that's all I really care about. Other than the choreography and cinematography, everything comes second.
But the movie fails in both points. People always complain about special effects looking live a video game...but for here, it's true. They LITERALLY look like they're from a video game. The actors are badly blue screened, and the effects are actually one step lower than Kung Fu Hustle which used *beep* effects well for comedic effect. Since this is a drama, it adds an impenatrable layer of cheese on top of everything.
There's one scene where a man is running from a heard of bulls. Not only to the bulls look like they were made for a playstation game 10 years ago, his legs spin in circles like a loony tunes cartoon. THis is supposed to be a big dramitic thrust early in the movie, but I was laughing out loud because it looked so ridiculous.
The choreography isn't every good either. Instead of using computers to enchance moves, it looks like a photo of the person is spun around, again giving it that loony tunes effect.
I love CG; King Kong, Revenge of the Sith, whatever people say about their quality as films, I think the special effects, while clearly computer generated, have a beauty and weight to them. But in the Promise they look awful. Not even mediocre, but really like it was filmed as a student project.
So, the trailer is misleading in that respect because they somehow rearragend the footage so it looked quite beutiful. But there's nothing close to Hero or Flying Daggers in terms of CG enhanced beauty.
That being said, the movie itself isn't too bad. I do appreciate the ambitions of the special effects, you can tell the director was trying to create this spectacular world. And while the story is cliched, the universal ideals of love and loss come through well within the epic framwork, and the soundtrack really adds to the drama.
So, the movie fails as a spectacle, and considering how important that is for these kinds of films, I can understand why people are so mad about it.
