The last couple of console generations, we've been sort of at a crossroads in terms of games as a medium. There has been a push in two directions for games. One is as an interactive movie-style experience and one is towards open world and freeform games. Neither's inherently wrong. Also, neither is a perfect fit for JRPGs vs Western RPGS because there's some overlap on both ends, but it's hard to define really what games should be. Even JRPGs derive from games which were a lot more freeform, even if not truly so.
However, technical limitations can still be a problem. Demands for voiceovers can limit freedom even within WRPGS. Look at the complaints over having a voiced main character in the next Dragon Age. As a result, it's fairly easy to complain about the loss of things we've gotten used to. Freedom (or the illusion of such) is one of those things that's easy to lose.
For a more cinematic style, it's even more difficult though. So at some point, there's a decision to be made in terms of how much you want the gameplay to interfere with your cutscenes. I'm being facetious, of course, but you get my point.
A lot of JRPGs are only RPGs in the sense that they inherit elements from prior games and are kind of "In the style" of those games. That's fine. I like a good story. A game with a good story will engross me. I'm not necessarily roleplaying, though.
I love the style of Japanese games, but when you look at the freedom of Western RPGS as opposed to Japanese RPGs, it's easy to see why people want them. But they don't need to be WRPGS. Maybe just take a few notes.
