I feel like Tchaikovsky is just some really good looking person who you want to be around but then s/he doesn't say anything interesting and you go buy a hot dog and try to think of something else.

But Saint-Saens is something else. I don't know anything about that kind of music, particularly. If the violin soloist moves like she's in a jerky silent movie but her dress is wispy fuschia not black and white then that makes a big difference.
