Exactly, it's all a cycle with these 'book trends'.
At least this series had the side characters like Cinna, Haymitch, and Snow to redeem it from the hellish teen romance drama, which happened the same way as every other young adult book's teen romance drama.
Your question implies that you assume only your age demographic is reading/watching.
The Hunger Games series has attracted people of many ages. I mean come on, my GRANDMOTHER is hooked on it. Your question is a bit unfair though because you assume that you and your peers are surrounded by like-minded and aged fans of the series, going crazy over another love triangle.
If you mean tweenies who just caught the tail-end of the Twilight hype and want to emulate school friends and/or siblings with "their own thing," then yes, I have absolutely no doubt that there will be a screaming fanbase of little girls (and boys) with home-made T-shirts with their "ship" on it.
However this doesn't hold true for everyone. Most surprisingly though, I have faith that the initial fans of Twilight will be the ones to keep their composure when it comes to this franchise. This has taken YEARS, and IN those years we (meaning MY age demographic, which is 19-22) have grown. We made it to see Harry Potter be put to rest, and in the middle of a beloved series going, we latched onto the nearest thing to emulate our raging hormones at the time (a.k.a. Twilight). During the years of Harry Potter dying, Twilight gaining hype with the youngsters, and getting mauled by over-enthusiatic underlings dressed ridiculously in theatres, our attention spans and intelligence level have grown (in most) to encompass more than angst and true love.
The reason I believe the initial Twilight fans will make the best Hunger Games fans is because we lived through (and occasionally initiated) the waves of screaming insanity for an undead virgin and an angsty fur-ball who has a problem with shirts; I don't know about you and yours but I'M definitely NOT looking to be a repeat offender. We have grown enough to appreciate intelligence and strategy in our literature. We had the Twilight series to assuage our hormones, now we need The Hunger Games to help us through life's "struggles."
And it should be pretty obvious why the older generation will not deteriorate into a puddle of emotions. Actually, my grandfather has read the first book as well and he enjoys comparing it to our government today. Granted he's neurotic and paranoid, but my point is every generation tries to find the point in a story that pertains to their current lifestyle.
My answer to your (slanted) question; EXPECT the screaming tweenies, they'll crawl to anything exuding pheromones. Have faith in the older generations though, we've got the years and experience on our side to help us comport ourselves with some decency. smile
In terms of the way it's panning out, general response to the Hunger Games is more comparable to the response to Harry Potter-- lots of people are really interested in it, and the book is well-written enough to stand on its own. The new Twilight is Fifty Shades of Grey, except it doesn't have a tween fanbase because no sensible parent will allow a tween to read it.
When the books came out: Wow these book are really good
When they announced the movie: Oh my god I can't wait for the movie!
When they started playing the trailers on tv: OH MY GODOFHSDFIOSDHFIOSD YOU SHOULD READ THIS BOOK!
When the movie came out: OH MY GOD THAT MOVIE WAS AMAZING OMG IOFHDOFOSDJF
When the fandom goes overboard: TEAM PEENIS TEAM CATO TEAM SNOW TEAMS LETS GO BUY COFFEE MUGS AND SWEATERS AND HEADBANDS OMG EVERYTHING HUNGER GAMES
Everyone: I'm getting sick of the hunger games.
One year later: THE HUNGER GAMES SUCKS OH MY GOD. Nothing gayer than the hunger games!!wptoj4t
♫I'm not yours, and you're not mine
But we can sit and pass the time
No fighting wars, no ringing chimes
We're just feeling fine♪
I only see the fandom becoming similar to the Twilight fandom (although not nearly as insane.) The difference between The Hunger Games and Twilight, in my opinion, is that The Hunger Games is actually a good series.
♪This is where we're supposed to be
Sitting by a broken tree
No tragedy, no poetry
Just staring at the sky♫
