Probably

The face Dr. Maki makes in that one scene where Date-San puts Kiyo-chan the doll in a boiling vat of oden was priceless. :lolol Best scene in all of Kamen Rider history.
I forgot which episode it was exactly but I remember rewinding and re-watching that scene at least 35 times and laughing out loud like it was a do not laugh challenge.

Do you think Kamen Rider have a better villain than Super Sentai's villain?

Most Recent Super Sentai have a villain who have a 1 motivation, Either Destroy the world or take over the world but why?! What is their motivation behind this?!

Kamen Rider usually have a villain that actually have a motivation rather than destroy the world or take over the world for no good reason

Both have their share of good and bad villains. It depends on who you choose to compare. For example, the villains in both Zyuohger and Ghost are some of their weaker aspects, Zyoh especially. Go back a couple of years, and we have Drive and ToQger, which both have brilliant villain casts.

Could another monster humanoid being work for a Rider similar to how Shin was expect for more PG friendly. I always felt like the idea behind Shin was great, but the movie was too boring for me to watch.

Could it work? Yeah, definitely. I don't think we'll be hitting Shin levels of monster, but I think somewhere along the lines of a more monstrous Black and Amazon could work.
It would definitely help enforce the whole connection of the rider and his enemies being fueled by the same power.

Suddenly on an Agito craze.
I don't know why. :lolol
So question time.
Who here thinks the G1 story from the S.I.C Saga stories should have been the Agito summer movie instead of G4?
To roughly brief you on what I am talking about, there is a short story segment on a monthly hobby magazine in Japan where they tell alternate epilogue or what if stories using sic figure diorama photos.
One of them had a side story of the G1 prototype suit which looks like a mechanized Kuuga and goes berserk and the protagonists have to find out why.

So, I got my friend into Kamen Rider. She liked stuff like Godzilla and the Japanese Spider-Man before, so it was pretty easy to get her into it. So far, she's only seen Ghost, but she absolutely loves it. We're trying to decide what series for her to watch next. She said her biggest interests are Wizard, OOO, Den-O, and Gaim. I suggested with going with Den-O next, since she said she wants more "fun" shows than "dark" shows. I eventually also suggested Fourze, since it's fun, and she eventually decided on Den-O, OOO, Gaim, Fourze as a potential viewing order.

What do you think? Any better ideas of where she should go from here?

Well, let her get through the shows she has lined up, first, I say. If she wants more "Fun" then Gaim is gonna be pretty disappointing after the 20 mark.

Well, she knows Gaim is dark, that's why it's placed where it is - get a couple of fun shows in first, then Gaim, and then another fun show after. Since Fourze was my suggestion and not one of the ones that caught her interest, it's later on.
