I really enjoyed those mechas as well, but the last batch of mechas that I really enjoyed was, believe it or not, Gekiranger.

magiranger got main mecha in two modes are magidragon and magiking

Gekiranger was a great mecha line that Kyoryuger reminds me greatly of. They both have very similar features at least from what we've seen of Kyoryuger. An initial three-part mecha where the Red forms the majority of the body while the other two form limbs, subsequent mecha attaching via limb-swapping, the lack of a sword, etc. I'm sure however that these similarities will end once the rest of the line comes in.

Anyhow, Gekiranger was a really fun mecha line with great-looking mecha and fun play features.

The last Sentai Mecha I really enjoyed was Goseiger, to be honest. But the last American MMPR Mecha I enjoyed would have to be OO. Show = Aweful/Zords = Awesome.

Back on topic.

As much as I honestly loved AbaRanger.. We already had Abaranger. You know?

Wow, Operation Overdrive? Operation Overdrive was clearly the start of the dumbing down of American Zords. They were simplified beyond reasonability. Both Jungle Fury and RPM were superior Zord lines despite downsizing.

Another Abaranger is not such a bad thing, and besides Kyoryuger presumably isn't going to completely rip-off Abaranger. I'm sure there's going to be a lot of new ideas in Kyoryuger.

Operation Overdirve is the worst, cheapest, and most inexcusable Ranger line that BOA has ever produced. They are PALE imitations of the Boukenger figures they're based on.

Ironically, their mecha was actually upsized instead of the usual downsizing, making all the flaws even more apparent. One wonders what the logic of upsizing, yet dumbing down the mecha was? It seemed really counterproductive. Definitely agree with you in that it's the worse Ranger line yet and will be for a while unless Bandai of America screws up massively.

Guys, I'm pretty sure Sentai meant the designs, not the toys.

Psh. Like it matters.

Well the Boukenger designs themselves were incredibly fantastic so it does :)
