Luke is the better one in my opinion. And I would be down with an insect theme, but it would have to be done properly. Would it be serious or comedic?

It can be serious if they try I bet. I think something on par with Shinkenger in terms of tone and mood would work.

I could see another season with the Shinkenger tone being successful. From what I understand, most audiences liked that show, but the more serious tone, simplistic toy line, and other factors of Go-Busters led to its demise.
Hopefully we start hearing mumbles and grumbles in about two months and get to see the new team in the Kyoryuger vs ToQger movie in January (if that is when it comes out)

More Gokaiger is ALWAYS a good thing in my book. :D

I think they should just keep the 40th anniversary low-key and have the 40th Sentai team either be an oblique homage to the Gorangers or just be a theme that Super Sentai hasn't done yet.

Like a Western theme. Pretty please?

My bro! :D

I think it should Shinkenger S2, cause it was the most famous sentai, right?

A Spaghetti Western inspired Sentai would be at the top of my wishlist.

Django Sentai Kaubōiranger

I honestly don't understand why people would simply want a re-hash or continuation of an old series. Why not something new? Something fresh?

Oh wait, because new is terrible. New is bad. Bad new. Bad.

It won't surprise me that they do Ninjas again since it been over a decade when we got Ninjas. Ninjas are popular in both Japan and the US.
