Everything the show did well:
-Really likeable cast from the heroes, to the villains and the sidecharacters.
-Consistently hilarious show from start to finish, easily the funniest Super Sentai show.
-Cool and funny action from start to finish both in mech and outside.
-Despite the show hardly ever taking itself seriously it manages to give every member of the team and even the mentors proper focus, give the villains development and make them feel like a proper threat and even manages to have a pretty endearing romance.
-Really great soundtrack.

Everything the show did bad:
-The final main antagonist Exhaus somehow manages to be kinda boring and forgettable in spite of his ridiculous goal.
-Radietta gets recasted with a worse actress later on in the show.

Reasons for the show's strengths:
Due to comedy anime generating more ratings than the previous Sentai season Ohranger, main producer Shigenori Takatera wanted to make a comedy focused Sentai unlike any before. He got Yoshio Urasawa to be the main writer because his experience on writing comedy anime and his work on the Toei Fushigi no Comedy series, in spite of him not having worked on Sentai before nor having seen any Sentai season prior getting involved in production. All of this led to the show being extremely unique plus also serving as an official parody to Super Sentai, Urasawa's experience with comedy really payed off and allowed the show to be consistently hilarious.

Reasons for the show's problems:
Despite the attempts of Exhaus to parody previous Sentai antagonists, the previous villains just were way funnier and original.
Due to Megumi Hamamatsu's poor health she couldn't continue her role as Radietta. The actress later alleged that reason she left was due to her being bullied by the co-stars Yuka Motohashi and Atsuko Kurusu, but it was later evidenced that Megumi was lying about this and ended up being sued for defamation. Considering this, maybe her 'illness' at the time was a lie too, since that case wasn't the only time she was caught for being a compulsive liar, and her leaving just mostly devolves on that actress just being a legitimately bad person.

Overall:
This show is extremely hilarious and manages to be a good Super Sentai show in all the aspects that matter. Highly recommend this show to anyone who's into comedic tokusatsu or absurdist comedy.
