Watching the same movie many times - Strange?

[Davy Jones]

There is most definitely topics about this matter already, but I don't feel like necroing something old. Plus, I think this might be -slightly- different from other similar topics.

I am going to see Avatar in cinema for my seventh time this Saturday. When I tell people that, they look at me weird, and they often ask me why I have seen it so many times.
What is really so weird with having seen it many times and still liking it? I don't get bored by it, it doesn't get "worn out".

I have friends who have played their favorite song(s) literally tens of thousand times. They don't get bored by that song, and I don't get bored with this movie. So what's the difference? I don't see people complaining about someone having listened to a track too many times, they rather admire their dedication to the song.
When it comes to Avatar, though, it seems to be considered being fanatic, border-lining to almost being mentally ill.

I wonder, what is really so different between a music file and a music+video file, that one "can" be listened to repeatedly, while the other "cannot"?

These are my thoughts on the subject.

Sincerely, Xynth.
