The thing is, RPGs are one of those genres where you sort of should have good writing. In JRPGs, often a great amount of time is spent talking to townsfolk and watching horrible cutscenes. And in Western RPGs, there's an inordinate amount of time spent talking to people and navigating dialogue trees.
If the writing fails in these games, a great big piece of the games have failed, and it is an impediment to my personal enjoyment.
The BEST of them will still be fun to play, and I'll look past it, but it's getting rarer and rarer for those gems to come out. It's gotta be something truly special.
SMT is one of my favorite jRPG franchises, with diverse games like Persona, Devil Summoner, Raidou, Nocturne and Digital Devil Saga. They usually have some pretty great gameplay. It's not the story I go into them for, however. I admire their (typically) adult undertones, and the way they weave their religious and philosophical symbology into characters and the world, but the execution tends to err on the typical anime contrivances with the same sorry, inexplicable character development as most jRPGs. I simply tend to ignore them and forget them, because the gameplay is something I like a lot.
