I tried OFF today, and in my honest opinion, doesn't live up to the hype. The battle system is very generic, and while there's tons of unique flavor, there wasn't enough to keep me interested.
I'm not sure it was ever commended for being "revolutionary". Just unique, and well executed. The art is simplistic and effective, the writing is great, the story is all over the map, the music is good, and the combat is serviceable. That's all it takes, I think.
