At this point I have now seen 20 Super Sentai from beginning to end and so I've decided to rank them up, going from least favorite to most favorite, and I would like to stress that every series on this list has something going for it and even if some were disappointing, they still had aspects to them that made watching them worthwhile. Also, there are going to be spoilers, though I did try not to give too much away.

The post itself is too long to be brought over to livejournal, so here's the dreamwidth link.

This super sentai series was pretty much conceived as a tribute to Science Ninja Team Gatchaman, though the similarities mostly correspond to the heroes' characterizations and the bird motif of their outfits.  It is also regarded as one of, if not the best Super Sentai series ever conceived.
