The Cars Franchise will always be the most nostalgic thing about Pixar, right next to the Toy Story franchise. The tales of Lighting McQueen and Tow Mater have always resonated with me. Personally, on its own merits, Cars 2 is a pretty decent film. It may seem like an idiotic concept at first, and some character logic may seem off, but it's still a fun action packed thrill ride which still excites me to this day. Cars 3 on the other hand, is similar to the first film in it's tone. And although this may be my least favorite out of the trilogy, there's a lot of great material in the film which should be reconsidered. The ending was nicely put together and had emotional weight, the animation was gorgeous and as well as the soundtrack, and the over all atmosphere resonated. It's just that some characters needed more development. To this day, I still believe the character of Cruz Ramirez is 10 times more annoying then Mater. Mater, at the least, had some thought out character development, while Cruz just seemed like a one trick pony. An annoying one trick pony. Sure her so called cliche "back story" was relevant, but that still didn't stop me from disliking the character. Jackson Storm, was also a weak villain. Literally zero motivations except for "Fuck you McQueen, I'm going to beat your ass because I have better technology then you, so Ha!" To be honest, the character of Sterling could have made a decent villain. But even then, there wasn't enough motivation to fully flesh out his character. Therefore, Cars 3 is the weakest out of the trilogy, mainly because of it's weak character development. At least it was a decent effort.
*Also Smokey was the best character, and I'll fight anyone who disagrees
