**Ten Things I Hate About You ** (thanks to cable) is fastly becoming one of my favorite movies. ( It has to be in the top fifteen right now.)
**Clueless **
**Tommy Boy **I don’t know if this qualifies at Teen or frat boy mentality. So I put it here anyways.
I liked Not Another Teen Movie a whole lot, as well as both American Pie movies.
Hmmm -
Have to agree with Clueless - transcends the genre
and American Pie - funny and feels okay to watch the tittilation because it seems to treat the female leads reasonably well
And will add:
She’s All That - My wife really likes this movie, so I have watched it a few too many Friday nights. Funny characters, and little more going on than just standard trash. And whild Freddie Prinze Jr. can’t act, his weaknesses are effectively covered up…
I love Ten Things I Hate About You and I don’t care who knows it!
Clueless, however, is my dirty little secret.
I like Ten Things I Hate About You and Clueless also, but the BEST Teen Comedy of ALL TIME is Whatever It Takes.
That movie is just so funny and offbeat it kills me! I have the DVD and have listened to the audio commentary more than once.
I have to agree with American Pie and Clueless.
Interesting both Clueless and 10 Things I Hate About You are modernised adaptions of classic novels (although via an excess of alcohol last night I forget which ones 
I also thought Cruel Intentions (again an adaption of a classic - Les Liason Dangerous) was a lot of fun, and Scream I/II although not sure they are “teen” movies as such
ten thing i hate about you
clueless
american pie (I. II is less good, but bearable)
cruel intentions
ferris bueller’s day off
the breakfast club
sixteen candles
Clueless is a true classic… but not as classic as Better off Dead, the absolute best teen movie ever made.
I also like Valley Girl quite a bit.
sirtonyh
clueless is an adaption of jane austen’s emma. ten things i hate about you is shakespeare’s the taming of the shrew.
both excellently done.
American Pie
Road Trip
I actually didn’t mind Dude Where’s My Car.
Dazed and Confused
That one with Jennifer Love Hewitt, ‘Can’t Hardly Wait’
The John Hughes classics (Ferris, Weird Science, etc)
No one has mentioned Fast Times at Ridgemont High?
Technically, Tommy Boy is not a ‘teen movie’ since it is not about high school or collage students’. Which I guess would mean Dude Where’s my Car isn’t either.
I really hate Julia Stiles movies. FYI all her movies are loosely based on Shakesperian plays.

Breakfast Club
Skulls
Final Destination
and Creul Intentions was entertaining to an extent
I never thought of Fast Times at Ridgemont High and The Breakfast Club as teen movies, though I suppose they are.
Must be a generational view. I didn’t have kids when those came out, much less a teenager.
Breakfast Club is one of my all time favorite movies, ever.
The Sure Thing
Better Off Dead
Say Anything
See a pattern here? 
I can’t remember, msmith, was Save The Last Dance (another good teen movie) an adaptation of Hamlet, or Macbeth?
But no One Crazy Summer?
Road Trip is hysterical. It made Tom Green palatable, and that in itself is a miracle. And Fred Ward was in it. DJ Qualls is the Anthony Michael Hall of the now.
Neither. It’s one of the movies that Julia Stiles is in that doesn’t adapt Shakespeare. Her movie after that “O” was based on Othello. And the Hamlet movie was just ** Hamlet**. I wish someone * would* do something with ** MacBeth** but it could only have her or Kenneth Branagh in it, not both.
Other non-Shakespeare movies she’s done include: ** Wicked; I Love You, I Love You Not; Down to You; The 60’s; The Devil’s Own; State and Main; and some I’ve never seen.

My favorite teen movies:
** Empire Records
Ten Things I Hate About You
Drive Me Crazy
Disturbing Behavior
Scream
Some Kind of Wonderful
Better off Dead
Hackers
Rock n’ Roll High School Forever** (who knew it was a sequel to a Ramones’ movie?)
Much to my husband’s and my sister’s chagrin, I love teen movies. I don’t know why, I just do. I’ve been trying to rent Ten Things I Hate About You and Clueless for the last week, but they’re always out.
And instead of listing every teen movie individually, I can only say that I agree with 90% of the movies listed in this thread. She’s All That seems to exemplify everything I like in a teen movie.
Again, I have no idea why. Perhaps my inner child is simply overactive.
Just thought of one not yet listed: The Princess Diaries. I don’t know if it counts as a teen movie or not, but also the remake of The Parent Trap.
Risky Business (1983)
Back to the Future (1985)
The Sure Thing (1985)
The Breakfast Club (1985)
Ferris Bueller’s Day Off (1986)
Adventures in Babysitting (1987)
Can’t Buy Me Love (1987)
Say Anything (1989)
Thanks. It is interesting to me that if a film maker adapts a classic and modernises it then it has a good chance of success, but if they were to adapt the classic without modernising it then most likely no teens would ever go see it.
I wanna say something like “what’s up with the youth of today” but I’m only 32 and it would make me feel old
