I think a lot of the issue comes down to what people consider JRPGs in today's landscape. A lot of RPGs coming out of Japan never get hit with the JRPG label because they don't mesh with the bulk of the genre, but then a lot of people complain that the genre is too stagnant and same-y.
In the past 10 years, there has been the following turn-based games with little to no creepy fanservice:
- Several Pokemon games, including Black and White, which is arguably the best in the franchise
- Shin Megami Tensei IV and several other remakes of spin-off games for the 3DS
- Dragon Quest XI, the Dragon Quest VII Remake and the 3DS Dragon Quest VIII port
- Octopath Traveler
- Valkyria Chronicles IV
- Radiant Historia (AFAIK)
- Fire Emblem: Shadows of Valentia (From what I've played)
- Bravely Default (Again, based on what I've played)
But there has also been many RPGs that have been excellent, relying on little to no creepy fanservice that have completely different combat styles:
- Final Fantasy VII Remake
- Demon's Souls, the Dark Souls trilogy, and Bloodborne
- Final Fantasy XIV and its expansions
- Kingdom Hearts III
- Final Fantasy XV ( I don't like this one, but I know a lot of people do)
- Xenoblade Chronicles (Some questionable (at best) outfits, but generally the plot plays it straight in the first game)
- Several Yakuza games, including the beat em ups, which heavily rely on random encounters, experience, equipment, much like most other JRPGs
And that doesn't include any of the critically acclaimed games that have more of the fanservice mentioned in this thread, including:
- Persona 4 Golden and Persona 5 Royal
- Fire Emblem Awakening and Fire Emblem: Three Houses
- Nier Automata
- The Trails series
- The Tales series
I love several of those 90's JRPGs, and there are absolutely some elements of the games from the best games of that era that have been lost over the years. Despite all this, there are still many JRPG's worth playing in the past 10 years that should lead people to believe that the genre will be alright going forward.
