I'm glad to see that Brave has now a 78% on Rotten Tomatoes so is slowly but steadily growing in reputation, so far there have been only 45 reviews so I hope more positive reviews will come. An 80% score is a high possibility. Besides, the "top" critics gives the movie an 86% so I think it shouldn't be dismissed so easily. As a Pixar huge fan who loves every single film they've done (except perhaps Cars 2 which I really enjoy but felt a little disappointed on it) I don't see nothing wrong to see a "traditional" Pixar film with a straightforward narrative, I think that despite any problem that the film may have it is still a worthwhile experience and I will go and see it day one (which in my case will be in July
).
