I addressed the story. To give an example, I reloaded my endgame save and played through the Real Ending roughly five times after I first beat the game, because it's just that good. I'm now about halfway through my second playthrough, and the writing remains just as amusing as it was the first time.

As for the jobs, they generally serve to mix up the gameplay in interesting ways, making clever use of the Wii's motion controls. And even if you think they're a pain, none of them last for more than a minute or two, and they're a total non-issue in New Game +.
