At least, you wouldn't be able to criticize this movie like how you would end up criticizing the anime. Firstly, this came even before the manga. You are going to follow the Chunin exam arc in just 2 hours. I mean for a change, its not 20 chapters or 20 episodes long. Let's appreciate that the plot has been set up beautifully and totally matches with the current era in the Narutoverse. Otherwise, the Shippuden's ending was almost perfect. It is also amazing that in just 2 hours, we still get enough idea about how the new generation characters are. Orginal Naruto fans and Shippuden fans too would enjoy this movie as their heroes Naruto and Sasuke do get an opportunity and do manage to shine in the battle. No doubt that the battle has been choreographed better in the anime version but it still looks perfect for a movie version.
Now that it is a fact that while adapting this movie both the manga and the anime added few more details or elements to the plot, I think it is fairer to treat this movie as a preview. Surely, that is bound to give a sense of something being incomplete but that doesn't mean you wouldn't be able to enjoy this.
I believe this should be watched before you start following the manga or the anime version.
