Reddit reviews Super Sentai- Season 2 (English Subtitled)

I should have linked it! Here it is on Amazon, what I watched. You can either watch it via a Comic Con HQ subscription or a Shout Factory! TV subscription. Dairanger, along with Kakuranger, are listed under Zyuranger as additional seasons. They all used Zyuranger's art in the app. You should be able to get a free trial. IIRC both subs include Zyuranger and Dairanger, but only one includes Kakuranger.

You can see in the episode listing whether or not an episode has CC. If it does not, that means the episode has no captioning at all. The captioning isn't baked into the video, it's through Amazon's CC API. From a quick glance, I can see Episodes 3 (what I watched and can confirm), 16, 17, and 35 have no captioning. Comments on the series say the final episodes were not captioned, but they seem to be here. Even with captions and various settings, I could never get the captions not to lag behind the video. It's really frustrating because I have no idea who handled these listings.
