It is an interesting dynamic, I just don't feel that it makes the show dark. I actually love how right after Faiz I ended up watching Agito because the shows are so similar but so different. The main plot point is similar, they just switch the sides of the opinion's on the dilemma. I just find that so interesting and almost a great study of sorts.

Yeah, I really have to get around to watching Agito, but I still have to finish Black, and then Kuuga's next.

Probably going to do what I did with Faiz and Kabuto. Starr both and stick with the one I prefer. But shouldn't I watch Kuuga before Agito?

You don't need to watch Kuuga before Agito. The show's are only connected by G3's suit being based around Kuuga's and a few throwaway lines in the first few episodes. Other than that there is no connection between the two.

Well guess I'll give it a shot between those two. Just hope it doesn't take me near as long to finish as it did Faiz. How long ago did I start watching that season? Hahaha.

It was about March or April :lol May have been February.

Just finished Kiva. With that, I can finally say I've watched every Heisei Rider series! No particular reason for saving Kiva for last, it's just the one that happened to get left behind.
I don't really have any interest in tackling the Showa Riders, so what am I going to do with my life now that I've nothing else to watch!?
I've been watching episodes daily for so long, it's going to be weird not having anything left...

We're two pretty similar dudes, so I'll be interested in how this plays out. I think Kuuga is one of the worst things ever made, period and I've never been able to make it past the first episode of Agito and now no longer want to when I found out it was another empty tale of Japanese media with forced Bible references.

Well I'm up to 39 on Wizard and by seeing toy reviews, the eclipse ring, Phantoms, oh what a way to tie everything together! Only about 11 episodes, not counting the two episode special. Then I'll have like 30 episodes of Hibiki and then, what ever comes next.

You could give Amazon a shot. One of the few Showa series that's fully subbed, as well as being an incredibly short series.
Or perhaps you could move on to Sentai?
