This movie goes too far thematically for what it is, and Pixar seems determined to hand over the spotlight to characters who aren’t particularly amusing. The “Cars” series has been a huge win for Pixar, allowing them to make money while solidifying their position as leaders in computer animation. I recall that these three movies were accompanied by such aggressive marketing that they felt like something being pushed on us. That's why I avoided seeing them back then. While the original film seemed fairly standard to me—technically impressive but with some writing issues—this one at least kept up the high technical and visual standards. The movie boasts beautiful cinematography and animation, which is typical for the studio. The realism is very well done, although it didn't feel as powerful or spectacular as in the first installment. I also noticed that the car races, a highlight of the original film due to their excitement and pace, felt less thrilling here and more repetitive. The voice cast continues to do solid work; Owen Wilson and Larry The Cable Guy were standouts, though Michael Caine (with his distinctive voice), Emily Mortimer, and John Turturro also did well. The real problem with this movie lies in the script and story development. I can see why they made Mater the focus—Disney and Pixar have done this before when a supporting character seems popular. And like those other times, the decision didn’t work out very well. Mater isn't funny; he's more absurd than humorous, and McQueen, who takes a backseat in this film, comes across as an arrogant and unlikeable driver. The dialogue doesn’t always land, and some of the jokes fall flat, though most are okay. I also have concerns about splitting the movie’s plot into two separate storylines (Mater's and McQueen’s competition with Francesco); it made the film more mature than necessary.
