I personally see Power Rangers affecting Super Sentai's fandom. I've seen lots of fans unintentionally view Sentai as "Japanese Power Rangers." Lots of fans still haven't quite gotten a hold of how Super Sentai's stories work, and unintentionally watch Sentai through how a Power Rangers season works. I know Super Sentai is quite popular, but it seems like a huge portion of its popularity comes from "Not being able to see Sentai for what it is." Lots of fans just follow Sentai just for the soul purpose of comparing them to Power Ranger seasons and unintentionally view Sentai as just merely "source material, that's better than it's adaptation." Every time I go onto a Zyuranger thread, I always see someone saying "Better than MMPR." This is how I think PR has impacted the toku fandom.
I can tell Disney wouldn't allow the Goseigers to show off their angelic wings.
This is one thing I've found annoying about the fandom. A lot of people grew up with PR and then only a few years ago discovered toku. They came in with the mentality that PR is just a kids' show and began watching mostly modern Sentais (since that's what's on, and it's the majority of what's subbed), thinking that this is what Sentai and all toku is. Hence we have too many people with this mindset that toku is just kids' shows to sell toys, and will forgive whatever outrageous thing that may occur in the programs because.... "Well, that's the nature of the beast. Toku is just wacky live-action anime meant to sell toys and entertain little kiddies. We're too old to watch this stuff but do anyway because we're geekly like that. Stop being an old fogie and just go with the flow. Learn to have fun" The problem isn't just with Sentai. The same attitude permeates Rider and the other shows as well. Only stuff like Garo ("Cuz it's sooooooo adult") escapes the defamation.
And for the record, Zyuranger wouldn't even be remembered were it not for MMPR. It's a waste of a brilliant premise, but gets way more credit than it deserves simply because "it's Sentai, and Sentai is dA kEwL! :buttrock:"
To both of you: Hey, for some of us, Power Rangers is the main, if not the only, reason we got into toku. Zyuranger gets a ton of credit, because that's the first Sentai PR fans learn about, even if the extent is that it exists and the Yellow Ranger's a guy.
Personally, I think Sentai and Rider are kids show, but extremely well done kids shows. Even at Sentai's most goofiness, it still beats Power Rangers' goofiness (don't tell me the episodes of Go-onger where Souske looked dead didn't leave any impression on you). Heck, when watching a Sentai, I don't think (much :anime

about it's PR counterpart or PR in general. Watching PR, however, I can always see where PR ends and Sentai takes over.
Yeah, Sentai sells toys, and it is obvious, and is meant for kiddies. I personally believe Sentai and Rider still does it with a touch of class.
As for Western influences, I'm probably a dummy, because I don't see them. There does seem a slight difference between the Abaranger-Go-onger era and Shinkenger/Goseiger, so there may've been a slight influence, but not as big as the Japanese version of Pokemon after the dub became well done.
Finally, to Fantasy Leader, yeah, Disney would've take their digital erasers and gotten rid of every feather of the Goseiger's angel wings or re-film those scenes if they were still doing Power Rangers.
