I've watched some of the Super Sentai versions, they are SO much better, but I was such a fan of the cheesy storylines of PR that I just had to stick with them growing up. I did like the ones where the Rangers were Angels, and then Pirate Angels and they had to stop their enemies...can't remember which series that was, but they were good episodes! Also watched the one where all of the past rangers reunited and it was so much more impactful in the Japanese version with all of the older series that never came to the US in them...really good.If you haven't yet, look into the PR comics that have been put out. I think by Boom studios. They did a really good job at expanding the universe and making it more grown-up.
Also, if you haven't, watch the original Japanese versions. Especially, Kyōryū Sentai Zyuranger. It was much darker than the American version.
Haven't heard of the comics, but I will try to look into them, I could get into a more grown up version, for sure!
