At first Jannah seemed incredibly boring to me, like "couches and goblets of crystal, rivers of milk and honey, mansions made of jewels..." blah blah blah. That would have been interesting to the Quran's primary audience, but to me it's boring. So at first it might seem like Jannah is boring, until you come to the verses that say, "and in Jannah they will have whatever they desire." Now things get exciting.
So there is stuff for everyone in Jannah.
I want to get a kitten in Jannah. My question is, if everyone has whatever they want in Jannah, surely people would want different things. Like, I would want a rainbow mansion that changed colors every hour, and a fountain that sprayed chocolate syrup on people. But if EVERYONE wanted things of that extravagance, wouldn't it get terribly chaotic? Colors and fantasy animals and jewels everywhere. How would God figure this out?
