Family-Unfriendly Aesop: Carranger vs Ohranger has Kyousuke learn an important lesson, that he should always judge whether someone's good or not based on their physical appearance.
Hollywood Pudgy: Youko. A big deal is made in episode 11 about how overweight she is with everyone from the monster of the week to news reporters commending on it. When she is shown in a bikini, however, she is very slim (not helped by the fact that Natsumi is shown in a bikini besides her and looks EXACTLY THE SAME).
Mis-blamed: Or rather, Miscredited - as noted on the main page, western fans will often refer to this series as the one that saved Super Sentai. However, toy sales for Carranger (11.8 billion yen) were lower than those of it's predecessornote to be fair, it's worth noting that Ohranger's toy sales are some of the highest in the franchise, at 15.9 billion; it's higher than Kamen Rider Ryuki, the highest selling Kamen Rider series, which sold 13.9 billion yen, and within the Super Sentai franchise, the only shows that come close to Ohranger's toy sales are Hyakujuu Sentai Gaoranger, which sold 14.5 billion yen worth of toys, and Zyuden Sentai Kyoryuger, which sold 14 billion yen worth of toys from sales in Japan alone, and in terms of viewing numbers, for the majority of it's runnote up until around the time the VRV Master debuted, Carranger had even lower ratings that Ohrangernote in fact, the lowest rated episode of Super Sentai in the entire franchise was episode 25 of Carranger.
Not just that, but the "car" theme was already used by Kousoku Sentai Turboranger, something that was referred to even back when Carranger first came out (and Gokaiger doesn't hesitate to use for a gag). Ironically, the full title of this series was originally the preliminary title for Turboranger.
It's also similar to Blazing Saddles in that it's a comedy involving an army of thugs sent to clear out a small backwater to make way for the construction of a lucrative transport route.
Tear Jerker: The death of Speed King Max in episode 9 is not played for laughs at all, and it's heartbreaking.
Win Back the Crowd: While many fans would argue if the series itself saved Sentai, they do agree that it played a part in giving Toei another shot in saving the franchise from cancellation, which is later filled in by Megaranger.
