Well, looking back at the early 2000's Sentai shows from Gaoranger to Magiranger. I guess you could say that from the story perspectives, they've kind of had some ups and downs. But, quality wise?!?!? I got nothing. Because like I said, I don't really care about the standard qualities of the show's productions or the ratings of toy sales, etc. I care more about the actual stories and character developments that each team have to go through. And so far, the only team that actually did grow more as an actual team, than as individuals are the Hurricanegers and the Gouraigers, because they really have matured since the last time we saw them. The Dekaranger also had to grow up from being a bunch of whiny kindergarteners playing "Cops and Robbers" to actual police officers reuniting to finish off one final case together before they return to their separate ways. Plus, they really have made something of themselves since their last battle during the series finale. Well, except for Hoji who is basically lamenting over the fact that he never get to do some amazing things now because he feels sad that he missed out on working together with the team. But Umeko is basically the stronger character in the 10 Years! After film where she realizes that yes, it is imperative to bring the team back together as long as they haven't forgotten where they've started and who they are. Lastly, Ban....seriously, they guy really has matured since we've last saw him. Now, he's officially become a true active Red Ranger that I would want to follow. Sure, he's kept some of his immature behavior from his youth, but it's been toned waaaay down. And, much like Umeko, Ban has to remind everyone that no matter where they are, as long as they don't forget that their hearts are in the right place and a part of SPD, they'll have nothing to worry about and they can always see each other again, whenever they want, or if they have enough free-time on their hands. Sen and Jasmine are doing alright. They didn't have much. And lastly, Tetsu actually gone up and is now the one taking commands. So, major kudos for him. Doggie Kruger and Swan are just....:meh: Still, nothing has changed for those characters.
Still, so far....the Hurricanegers and the Dekarangers are the only ones who have the stronger chemistry among their respective cast members. I hope something like that happens let's say the Abarangers or the Magirangers. That is IF they're gonna get a "10 Years! After" reunion special, respectively.
