I didn't like Persona 4 very much. It had some high points, not enough to merit the praise.
The characters were pretty shallow, there was an awful lot of bad comedy, and the story was disappointingly formulaic. It only surprised me a couple times and even when it was for the better, it frequently did things with the surprises that bogged them down.
Also, one-note evil for the sake of being evil villains are super lame. This applies to especially strongly to the final villain.
Basically the story and characters were flat and the gameplay wasn't terribly engaging.
So.... ::]::
