There were things I liked about the main character: he refused to live the way anyone else thought he should, so he didn't get a regular job and chose instead to work as a street performer, he wore pajamas all the time as if they were regular clothes, he occasionally played and cavorted and mugged like a kid, etc. He definitely had a Benny & Joon vibe going, especially with the constant hat wearing, but (unlike the Johnny Depp character in that movie) he wasn't just dismissed as charmingly quirky ... his unhealthy obsessiveness and inability to live an adult life were acknowledged as real problems.
Part way into the movie, I started feeling uncomfortable, because I thought they were going to make this character's dysfunction lovable and imply that his obsessive beliefs and behavior shouldn't really be interpreted as creepy.
Then the main character's brother started ranting about how the guy was mentally ill, unstable, and unable to function in society, and that something needed to be done. I agreed with most of that except the "mentally ill" part, because I didn't think he was crazy; I just thought he was messed up, and I thought a good therapist could probably straighten him out.
Then our "hero" finally got up the nerve to tell his beloved how he felt ... and when he "romantically" told her that he'd been secretly stalking her for more than a decade (since their childhood friendship/romance), moving from city to city, state to state, to be near her, it wasn't the great climactic love scene that he'd been imagining (and which many movies would have presented). Instead, the heroine seriously flipped out, told him to go away and never come around her again, and insisted that what he was doing was creepy and unhealthy.
So the guy went away, despondent, the whole center of his life torn away, and then made his peace with the death of his parents, made his peace with his brother (who was very supportive of his efforts to move on), apparently made his own life (still extremely eccentric, but seemingly stable), and (some time later) wrote his beloved a letter that basically said, "I realize now that I was being a freak. I'm doing my own thing now, and I hope you're happy doing your own thing. Ciao."
For reasons that were a little complicated and semi-understandable, the heroine chose to go find him after receiving the letter, which resulted in the best line of the movie, when our formerly-creepy-stalker hero leans over and whispers to our just-tracked-him-down heroine, "Are you following me?" Ha!
So I enjoyed the movie, even though it wasn't what I was expecting. Earlier in the day, I'd watched Ashton Kutcher in No Strings Attached ... much more the brainless pap I was looking for.
And today I found out that Strictly Ballroom is available through Netflix streaming, so I guess I know what I'll be watching tomorrow! (Not sure how many times I've seen it before, but I can always watch it again.)
Conclusion: Netflix streaming is extremely convenient when I'm sick.
