I admit I am not a fan of newer sentai series because its so obvious that they aim it more to kids. For example the ending songs/dances or the repeated themes like ninjas, animals, dinosaurs. There was something about Lupinranger vs Patoranger which was this vs concept that they tried out. Yeah it's been reported that this show did not reflect well at all in terms of toy sales which is their main target but to me my purpose to watch super sentai is not for the toys but for the enjoyment of the show in other terms like the plot. This show was not the best I have ever watch nor it was not the worst thing ever but it was a good show.

Story: The motive for an usual sentai team is that people gain the power as a ranger then they use it to defend the world from monsters. It's simple but it can get worn out and become bland. Now for the lupinrangers, they have an interesting motive to why they are lupinrangers which is because they need to gather/steal these collection pieces from the ganglars(monsters of the show) in order to make a wish so that their loved ones can return alive again from a tragedy that happened. See for the lupinrangers it's not really about destroying the monsters and protect the world although it happened just a bit, but they just want to take the collection pieces and flee. It's something different and interesting for a sentai team to do and you wonder if they would continue to be lupinrangers when they gather all the collection pieces because their goal is done and they don't have to be lupinrangers anymore. Let me say that this show was heavily more focused on the lupinranger in terms of about everything. The Patorangers are a police team, they protect the world from the ganglars and arrest the lupinrangers. The Patorangers are more of the normal sentai team. The addition of the 6th ranger Noel was another new interesting idea because hes a member to both teams but again is more on the lupinranger's side. I like the guy, he has a good personality but his backstory was lacking.
The lupinrangers have the best characters and I was cheering for them. Each of the three have good backstories. Although I wished they could have done more a bit with their backgrounds. Now to the Patorangers, they were shafted in this show. I couldn't really care for them except for Keiichiro because he played a key role to Kairi. The other two weren't focused well enough to make me care for them. The Patorangers were mostly used as the comedy characters. Something interesting during the show was how would these two teams interact with each other. Sure enough the Patorangers were just good customers to the lupinrangers cafe. Only Kairi and Keiichiro had a good interactions from the two teams and was the best relationship from the two teams. I thought the Umika and Sakuya pairing was a bit dumb especially for Sakuya's side of liking Umika it wasn't explained well. My favorite relationship of the series was Kairi and Umika sharing a brother/sister relationship. I even liked that episode of when Umika's dad appeared.
A big part of this show that kept you watching was the reveal of the lupinrangers identities and let me tell you I was let down of how they did it. I think they could have don it better or heck not even do a reveal since the patoranger knew by the end who they were. Maybe they could have build some small side characters that were friends of the lupinranger like there was this neighbor lady that knew Umika but later on was never shown again. If they still went with a thieves reveal, it should have been done around episodes 30-39 to build an plot of the lupinrangers being on the run. I am glad that at the end they stayed to the vs concept with both sides not becoming one team but still competing against each other. The story of this show was very good but not perfect.

Acting/Cast: The actors of Kairi, Keiichiro, Umika, and Noel stand out the most. I do think that they could have added more minor side characters like older people as friends to the lupinrangers.

Music: The main reason I actually watched this show was that the opening song was so catchy to me. I was already hooked to this show because of the song. The opening song is a duet of two songs by different artists and its so catchy. I also liked that this show didn't have an ending dance/song because of how more serious this sentai was. Lupat's opening has become one of my favorite sentai opening songs ever.

Re watch value: Hmm this series did have lots of filler episodes and I only enjoyed one of the sentai teams but I may one day re watch this series but it won't be on my top priority list.

Overall : I thought that this vs concept in super sentai was something new and interesting to do and would love for them to do another series like this. I think this is one of the better sentai seasons. I wish more sentai series would focus more of reality/life in the shows with the characters. It could have added a bit more to this show. This show is good at its characters and the plot is simple, different, and interesting. If your not a fan of the more childish sentai series then this is a good sentai series to watch.
