Everything the show did well:
-Big One/Banba is a really likeable character.
-Some cool spy action here and there.
-A few cool monster of the week.
-Really cool aesthetics.

Everything the show did bad:
-The team just comes off as generic most of the time, the initial commander too.
-The lack of proper main villain generals is disappointing due to the main antagonist duo being pretty boring.
-The majority of monsters of the week are pretty forgettable.
-As likeable Banba is, he is not likeable enough to make the show enjoyable and alongside him comes Tamasaburou who I never was able to find funny, but this might be a personal issue.
-The show overexploits the "film-reversal" technique of the original Kamen Rider show, which removes most of the impacts from the fights.

Reasons for the show's strengths:
Due to the show's low rating they brought veteran actor Hiroshi Miyauchi who had played previously played Aoranger Kamen Rider V3 to increase the ratings, and ultimately ended up being the best character of the show.

Reasons for the show's problems:
In order to differentiate as much as possible from the previous work Goranger, they tried to make the show have a much darker tone, however the staff didn't know how to properly do that and ultimately ended up with both the heroes and villains feeling boring and hardly ever entertaining. There was supposed to be a time travel plotline but ended up being scrapped due to feeling too detached from the setting, this resulted in the villains not having any direction. The show then was cancelled due to bad reception and had a whole quarter removed.

Overall:
This show just doesn't have enough going for it. Having one likeable character doesn't really fix all the other issues or suddenly makes the rest of the cast suddenly entertaining. The show's just very bland overall and I can only recommend it if you REALLY like Big One and even then he gets introduced on episode 23. This is the worst Super Sentai out of the ones I've seen so far.
