We'll have to wait to see the performances to judge, but it sure is hard to think of the Frodo role as "supporting".

I know! - But there is no clear lead either. We'll see!

I don't know, I see Frodo as clearly more important than anyone else in the story, I don't have any doubt that he is the main protagonist.

If the movie muddies this point, I would see that as a flaw.
