When I compare all the villains in Yuuya Takahashi's works, I think the villains in the Geats series are not as interesting as the villains in Ex-Aid and Zero-One because of lack of future world details in the Geats series and a boring DGP villain background. Suel is easily one of the worst Kamen Rider final bosses in my opinion.

Some series examples, like Ghost and Gavv, have more interesting world settings for villains than the Geats villains.

I agree.

One of the last straws for me with Geats was when we finally got through all that stuff with Ace?s mom and the dude in the tweed jacket and the show immediately brought in another evil DGP producer.

I really wanted Zitt to be Suel's true identity. If the writers take this route, I think Suel could become a more interesting villain.

Unpopular opinion for Valentine's Day: Toei's Spiderman's Hitomi is Spiderman's best girlfriend. At least in live action.
