I've been watching this series lately. I am surprised to say that it is pretty good! The story line is not bad, although it does have some cheesy moments to it, like the whole run-in introduction of the rangers. The enlargement of the Origami zords by writing 大 on them is pretty cheesy too. Some of the moves pretty cheesy as well like the swordfish head attack on the megazord. Okay, so a lot of it is cheesy. But overall, I really like this series. It reminds me a lot of Mighty Morphin Power Rangers like in the old days.
I am currently on Episode 9 of the series.
