It's the same thing when I said Deboss are the best villians in recent memory. I was basing that off series' I've actually finished. So Goseiger, Gokaiger, and now Kyoryuger.

That's a short list for a guy called Sentai. :p

You need to expand your repertoire :lol
Spread your wings! Dive into some Deka, Geki, or the first Gosei team, Dairanger :p

Or Go-Busters, for crap's sake. You really can't go talking about best recent villains when you haven't seen Enter in all his glory.

Seconded. Enter is my fave villain for a reason.

I'll ask the same thing Locke did when he started watching Goseiger. How many episodes before it gets good?

Hard to say, but I'd say there's some cool stuff at around ep 5?
Also, watch Shinkenger. And Gekiranger!

I saw Shinkenger already, I sat through Samurai :lol

This is one of those things that's going to vary for different people. Some are gonna say when Beet/Stag Buster were introduced (episode 15), some are going to say when the changeover happened (around episode 29-30) and then people like me are going to say Go-Busters was always awesome :p

So 15 then :lol
