My MINOR problem with '500 Days of Summer' that has caused outrage

Okay. Let me set up this story.

So, over the weekend, I saw the movie 500 Days of Summer. And it was...okay. There were things about it that I thought were really clever, there were things about it that I thought were cute- all in all, I'd say it was a good movie. Nothing spectacular, but definitely not bad. Just an enjoyable, light, predictable romantic comedy. And there's nothing wrong with that (and actually, is it even possible for a romantic comedy not to be predictable?).

While I was watching it, though, one scene stood out to me. The scene where Tom (Joseph Gordon Levitt) is singing karaoke. Actually, all the scenes where anybody was singing karaoke, other than the drunk dude singing "I'm Proud to be an American". I'm not familiar with the song Zooey D...?'s character was singing, but Tom was singing a Pixies song. Here Comes Your Man. In a karaoke bar.

I don't think so. Tell me, have you ever encountered a karaoke bar that plays indie music? Alternative music? Don't even bother telling me the answer, because I know it's no. At a karaoke bar, you hear top hits. You hear drunken people ruining Michael Jackson songs. You know why? Because EVERYBODY knows 'Billie Jean', and EVERYBODY can be amused by some drunk chick slurring out the lyrics. What kind of uppity, smug karaoke bar would have "Here Comes Your Man" preset on their machine? Only a handful of people in the bar would be familiar with the song, and everyone else would be going, "...what is this?"

I'll tell you why Joseph Gordon Levitt's character is singing a Pixies song- because 500 Days of Summer wants to be an "indie movie". And guess what- it IS an indie movie! The soundtrack consists of alternative music, the way they tell the story is inventive and creative, and it wasn't made with a huge budget or, necessarily, A-list stars (although I would argue that JGL might be classified as A-list post-Inception). The makers of this movie thought that they couldn't have the characters singing 'Billie Jean' or 'Private Dancer' or what have you because a popular, mainstream song wouldn't be "indie enough".

To me, this scene took me out of the movie. It shows me the hand of the creators. Everything else about this film was organic, but that scene was unrealistic on purpose for the sake of appeasing smug viewers. There, I said it.

Apparently I've upset some people with this opinion and been told that I have a problem "suspending reality". Well, my favorite book series is Harry Potter and I grew up watching Star Wars, so I find that doubtful. Yes, there are fantasy scenes in the film, but they are clearly fantasy scenes. Most of the scenes in 500 Days are based in reality. Flirting at the IKEA store, sitting on a bench and looking at buildings, getting in fights with your significant other, singing karaoke at a karaoke bar. Like I said, it's an obvious play by filmmakers afraid to have anything remotely mainstream in their movie, and it bugged me.

Honestly, it wasn't even a big deal to me, but the moment I mentioned it I had rabid fans telling me I couldn't suspend reality and that I was wrong. For the record, again, I liked 500 Days of Summer. Some people love 500 Days of Summer. Either way, I should be able to critique it however I want and not be accused of misunderstanding something.

THAT IS ALL. Thoughts?
