Yeah, I hate JRPGs, but if you're going to play any RPG it takes way more than an hour to get into them.
I wasn't digging either Fallout 3 or Oblivion for the first five or so hours, then gradually got into them and by 10 hours or so I was hooked. Put 70 some hours in Oblivion and it's DLC a couple years ago, 52 into Fallout 3 and its DLC over the past month or so with a bit more I want to finish up.
Some action games, shooters etc. you can play for an hour or two and if you're not digging it you probably won't, but RPGs are notorious for starting slow and taking a while to get into--both JRPGs and western RPGs so those take longer to get a feel for.
So the genre really isn't for people who don't like slow starts/learning curves etc. I kind of fit that bill, so I just play 1-2 RPGs every year or two.
