Is it possible to attach discussion board to a node? I have a content type called "Movies". I would like to create discussion threads  under it similar to discussion threads in imdb.com under a movie. I have tried the advanced forum module and also brain forum module. They don't seem to do that I have in my mind. 

Is there a module which does this job? I think I will have to use advanced forum module and use a content type for forum discussion and then use entity reference and entity reference prepopulate to link it to the other content type. Is there a better and cleaner way to do this?
Use the core comment module.
