Come for the X, Stay for the Y

You're browsing around, and you find out about something that looks neat. A new TV show, a new movie, a new book, maybe a video game. You don't know anything about it, but it looks neat. Something about it jumps out at you. Could be the humor, could be the action, could be the eye-candy. So you decide to try it out.

And it turns out the show is pretty good, too, and you like it. But over time, you start to like it for a completely different reason. This show with the cute lead character actually has an interesting side character with an in-depth story that you're really getting into. Or this movie might be very funny, but it also has some great undercurrents of drama that you weren't expecting, and that really jump out at you. Either way, you end up really liking the show/movie/book/game/etc for a reason completely different from why you started to check it out.

This is an example of Come For The X Stay For The Y. You originally start to get into something for reason X, but in the end, it's reason Y that causes you to get hooked and stick around.
