Everything the show did well:
-Really likeable cast overall.
-Consistently amazing action and battle choreography, arguably the franchise's best.
-Great jazzy soundtrack.
-Really interesting twists and plot developments.
-Most the side Riders that only last one arc manage to be memorable and likeable.
-Aside from the main antagonist, while not really impressive the villains in the show all manage to be pretty memorable and likeable.
-Great final episode.
-The show has a lot of style to its direction.
-The gimmick of having the Riders participate in games makes every two-parter and battle really memorable and different from other tokusatsu.
-Extremely good use of form changes.

Everything the show did bad:
-Girori and Ace's characters and acting feel kind of inconsistent at times.
-The show's writing quality drops in the second half. In the third quarter Keiwa barely gets to do anything and Neon does some really dumb decisions. In the last quarter the conclusion to both characters' arcs start and finish there, while their arcs make sense and were properly set up and foreshadowed in the first half, they happen so fast which makes their emotional weight lacking. The second half is also lacking due to the show having one of the most generic and forgettable main antagonist in the franchise.
-Despite the rest of the villains being individually likeable, there's too many of them around simultaneously to be properly developed.
-While Michinaga is a likeable character overall, the show tries to paint him as an anti-hero which doesn't really work since there was no way for him to know the truth behind his actions.
-The cast barely critizes Neon for her actions in the second quarter which makes a lot of the aspects of said arc feel like filler.
-The show feels overly critical of Keiwa's way of thinking. While he's extreme and naive, due to the nature of the deaths of the people he wants to revive it feels like there's hardly anything wrong with his goal, it's just his actions in the second half that's a problem. Yet even prior Keiwa's wrongdoings the show treats him like a punching bag and as if his goal is too naive despite making sense which makes Ace feels like an hypocrite at times.
-Hallelujah Win feels heavily sidelined.
-The world of the supporters/sponsors doesn't get explored enough and it's mostly just left to the 4 Aces movie.
-While not strictly necessary for the plot, a considerable amount of Hallelujah Win's and Niram's character development and world-building is left to the Kamen Rider PunkJack special.
-Tsumuri feels underdeveloped.
-The Riders motif feel pretty boring and basic compared to other seasons.
-The show has artificial humans as a plot point, which isn't a bad thing but since the 3 Takahashi Rider shows aired so close to each other it makes this plot point feel repetitive if you're watching the seasons in order.

Reasons for the show strenghts:
Main writer Yuya Takahashi learned from his past mistakes and actually did think the secondary rider character arc and gave the characters downtime for them to interact while still keeping his fast-paced style of writing. He made a really interesting setting.

Reasons for the show flaws:
Takahashi wanted to make too many villains simultaneously which made it so the villain cast isn't properly developed.
The staff didn't properly tell Ace and Girori's actors how their characters were supposed to be because they were afraid they would spoils plot points, so their characters are kind of inconsistent.
The show's toy manufacturer Bandai changed the show's second half for the worse due to delaying the cast upgrades. This resulted in Keiwa and Neon not getting much to do in the third quarter and their arcs concluding really fast without having proper weight. This also resulted in Hallelujah Win not being able to transform into Punkjack since they repainted his suit for Neon's arc but said repaint ultimately ended up being used in the final quarter rather than the third, making it so they weren't able to repaint it back on time. This rewrite also force them to change who the main antagonist was supposed to be, which resulted in the impromptu boring antagonist Suel.

Overall:
The show is the most 7/10 show in the franchise which makes it an excellent show for a beginner to Kamen Rider I guess. It's just great and interesting enough to get you watching but it has enough flaws to keep it from being a really great show so it will get you excited for other shows in the franchise. Overall pretty great show but not really a stand-out one.
