I've seen the 90 minutes version of "Dumpling", it's much better. And I think it will tell you more than what you saw on screen. I never think it ended too abruptly. The director had already passed on the message he wants to tell. And PLEASE, NEVER suggest a Hollywood remake! Hollywood only rapes Asian horror flicks with screwed-up remakes!! Look at The Ring, look at The Grudge and Dark Water. My goodness!! There are always some flaws in movies, Hollywood ain't perfect! They made so many stupid movies every year. So do you suggest Asia to remake all of them? What I would say is, Asians have more heart in making movies, rather than Hollywood. Even a lot of European movies are much better!
