VIDEO : Nathan Fillion & Kerry Washington Join Cars 3

An award magnet, animation studio Pixar has spent the last few decades establishing itself as one of the all-time best sources for quality animated films, achieving a track record of excellence rivaled by only a small select few. For Pixar?s first 15 years in existence, every single one of its films managed to become a critical darling, with all but one earning upwards of 90 percent on review aggregator Rotten Tomatoes. That one was 2006?s Cars. While Cars? 74 percent rating is far from a failure, it was the only break in that long chain, at least until 2011 sequel Cars 2 managed to become a full-on critical bomb, earning only 39 percent.
