Why the 80's sentais had the best ratings than today ?

I heard Bioman was pretty popular.

I'd be down for that. :)/:p

speaking of bioman, I bought an english dubbed bioman dvd about ten years ago and after watching it i lend it to a friend. Now i want to kill that friend because he hasn't returned it since then! He said he lost it WTF its extremely hard to find one now....

Seems like the people cared about their "shows" before but now its all about toys.

Isn't that the truth.

But this don't answer my question.

no idea on the ratings but if youd watch the older series you will find the answer yourself. Most of them show or tell the origins of their powers, heroes are more closer to "reality" and the actors themselves can really act. The stories were also a little deeper. Like in Bioman, 1st yellow-four died, so they had to scout for another one. Also, there are "more" action, drama and romance in the stories before now it's more comedy, gadgets and mechs.
Its all money oriented.

man! i only watched few ep then i dropped it. i was so disappointed...

I have no idea what you're trying to say.
Damn near every series, regardless of era, tells the origin of their powers. Bad actors are all around the board, and that money oriented series design is the only thing that keeps Sentai on the air.

As for stories and drama, Yellow4 dying isn't "Deep story telling" that's just "The actress wanted to leave the show, so they had to scramble last minute." Many early series had incredibly shallow stories. Typically amounting to "Monster shows up. Pose. Destroy monster." At least in current series they try to create and weave a storyline into their series. Many early series were MOTW series in true fashion.

The interest of what kids want to see shift from generation to generation. Or should we merely shove what we perceive as better down their throats and force them to enjoy it?

You know what? Fuck it.
Super Sentai was always money oriented. They didn't make Bioman to show a dramatic series of love, death, and heroics. They made Bioman to make some mother fucking money. And the moment toy sales began to lower, they'd shove some new gadget into the series to put that shit on the shelves.
They did that thirty years ago. They did that twenty years ago. They did that ten years ago. They do that today.

yes. its hard to explain . its the kids and probably what you said about interests . i was just comparing the current actors and the actors then. cuz some of them actually practice martial arts and do their own stunts. but its as you said.

*Nods*
