Samurai Sentai Shinkenger (English translation Samurai Squadron Shinkenger) (2009-10) was the 33rd installment of Super Sentai, and the first Sentai since Jetman that didn't get adapted for Power Rangers. That is, until Saban bought back Power Rangers from Disney and decided to adapt Shinkenger for next year's Power Rangers. Shinkenger was a more serious oriented Sentai, though it still had a fair amount of comedy, especially the V-cinema movie.This series had a samurai motif which many fans had been waiting for and was a season of many firsts. As well as being the first samurai themed Sentai, it was the first Sentai to have a team up with its sister program Kamen Rider (Kamen Rider Decade) and to feature a female red ranger, although she was only present for the last six episodes. It is also arguably the most culturally "Japanese" of all the Sentai, which led to ridiculous speculation that Shinkenger was "too Japanese" to be adapted for Power Rangers. Shinkenger is one of the most popular Sentais, and helped bring a lot of new fans to the Sentai franchise. Fans love the samurai motif, as well as the cast, a very serious red ranger, deep character development, strong villains, and overall strong plot. However, like any show, Shinkenger isn't without critics. Critics of the show complain that the plot focuses too much on Takeru, has a hiccup in the middle of the season, and has mecha overload. Others criticize Kaoru, the female red, for being a spoiled brat, although this criticism mostly comes from Takeru fanboys.
Among 2000's Sentais, Shinkenger has one of the best casts along with Dekaranger and Boukenger. Character development is strong in this season, not only among the rangers but some of the villains (like Dayuu and Juuzo) are well developed. Even some of the side characters, like Jii, are well developed. The only character that was really under developed was Kaoru. Some of the villains, like Dokouku and Juuzo, are among the most fearsome and evil villains in Sentai. Shinkenger has a very strong plot. While some criticize the plot for being too much Takeru centric and stumbling a bit in the mid season, I disagree. Takeru gets the majority of the focus but the other characters got proper focus as well. As for the mid season stumble, I think it's during this stretch when characters such as Genta and Mako get strong development, and among all the mecha's, the Ushi Origami had the strongest story, which also came during mid season. The theme song is also awesome, which was by Psychic Lover, who I consider to be the Ron Wasserman of Sentai. The two team-ups so far, with KR Decade and Go-Onger are both good team-ups and the second movie, the V-Cinema movie was also pretty good.
The season does have a mecha overload problem, wit
