Not really.
People will either like or hate it. Dungeon exploration is a pain in the ass. Also some of the gameplay mechanics are not too hot.
Only general positives is how quick combat can be and the characters events are full voice.
While the JP reviewer is known to be ungodly fast at clearing titles its around 18 hours is what they clocked in for their first play through.

In regards to amazon only 9 people reviewed it so its sitting at 4 stars, but thats 9 people now. And the price is low on both the LE and standard ED. Think the LE was even priced lower for whatever reason. So take that as you will. Dont really hear too much about the game over here. It kinda came out and that was it.
For technical issues game apparently had freezes and such so saving often is suggested. No idea if it was fixed. Was not something that would occur often but it can happen which was the problem.
Also while there are only 2 reviews here this site is also not too bad for how players in Japan thought about a title. As folks who post there are required to follow a specific format when doing reviews.

Think the site too does not allow reviews to go out till a certain period of time has passed after a games release. To prevent the asshattery we always see on Amazon...
