The amount of cutscenes you'll be watching, and the length of some of these cutscenes is just ridiculous. Metal Gear Solid is nothing compared to it. What's even worse, a lot of these cutscenes are stringed together, so that when one cutscene is over, another one will start playing. When a cutscene is finally over, you get to walk to the next area, and another cutscene will start.
The combat is enjoyable though, even though it's way too similar to earlier installments in the series. What's interesting though, is that in some parts of the story, you get to choose the way in which you'll play the game. Each choice makes for different and/or tougher game experience, and each rewards you differently. So that's neat. And the character roster is huge, bigger than any other Naruto game to date.
The storyline takes about 7 or so hours to complete, and 4-5 hours, you'll spend watching gorgeous but overly long cutscenes, resulting in a very boring experience. For the hardcore Naruto fans, this might be enjoyable. If you're anyone else, stay away. You won't be amused.
