Because Go-Busters was so unpopular, the Toei execs now thinks it's wrong to do anything like Go-Busters, including good mecha battles. Ace is one of the best highlights of the show. Ace is still awesome even in the finale...all 3 or 4 of them :p

Because it's Dekaranger and everything about it's awesome.

I'm debating whether I want to watch Shinkenger next or watch PR Samurai. While I enjoyed Shinkenger, half of the series could go without any issue to the plot (god, now I sound like Locke and Split), the villains did nothing but drink and be lazy, I hate Genta with a passion, but most of all, I hated Clusterfuck-Oh. Well, I wasn't a fan of the mecha that much at all, as I thought the origami thing was dumb, but the overload of mecha on top of mecha was ridiculous. On the other hand, I thought Juuzo was awesome and the ranger cast (sans Genta) was amazingly solid. They all had great chemistry with each other. I doubt PRS will have the same, but I do want to at least watch the series once.

The only thing Samurai will do is make you appreciate Shinkenger more. Samurai is nothing but Shinkenger verbatim with the only changes being bad acting (The worst of Power Rangers), unfunny Bulk and Spike scenes, and a butchered back stories for Juzo and Dayu. Also, the actor who played Samurai Gold based his performance off of Genta's performance, so you'd hate him anyways. If you've seen Shinkenger, you have no reason to ever watch Samurai unless you just want to watch ever PR episode ever.

...I actually enjoyed what i watched of Samurai.

And I'm actually enjoying Operation Overdrive.

Klonoa, I'm scared. :(

Well that is just it, I do want to see every PR series some day like I would love to do with every Sentai and KR series.

Join us, Dr Kain!

If you watch Shinkenger, my advice is to watch the first fifteen or so episodes, then jump all the way to the last five. The middle section of Shinkenger is so bloated and it just feels looooong and so boring.

There's never a good reason for watching Samurai.

I forced myself through Operation Overdrive, Samurai, and Super Samurai precisely for that reason. I only ran into trouble with Mighty Morphin' Power Rangers (especially when you consider the fact that I'm still on episode 2).

Besides, I will argue that Super Samurai has the best Red Ranger in Power Rangers history in the form of Lauren, so there is that.
