On my quest to watch every sentai, one month ago or so I started watching Zyuranger, Abaranger and Kyoryuger.
Yesterday I finished Zyuranger. It has some pretty good moments, but overall... it's a pretty boring sentai. It's like they took some of the few boring Jetman episodes and turned into a sentai. And Jetman even had some better "kid of the week" episodes than Zyuranger. A few great episodes made it worth watching, anyway. The evil Burai Arc and the last five or so episodes were my favorites.
Today I'll finish watching Kyoryuger, only two episodes left. Tomorrow, Abaranger.
