I kind of liked the teen comedies of the time. My favorites include:
Sixteen Candles
Weird Science
License to Drive
Fletch (the original, not Fletch Lives)
I had watched the last two movies so much that I had them memorized.
As for TV, one show I like from the late '80s/early '90s is Charles in Charge. Very simplistic, but enjoyable. I like shows where I don't have to think too much.
Edit: oh, man, I can't believe I left out Weekend at Bernie's. Oddly enough, that movie is my 4-year-old niece's favorite film.
I haven't watched Weird Science in a long time, but I loved that damn film. Even the Oingo Boingo song for the film is great.
Nicole Eggert (sp?) helped make Charles in Charge even better
. And....Willie Ames? Is that his name? Buddy? I haven't watched this show since late80's and I remember totally random crap.
I love all the movies you listed.
The original Fletch...the pacing, the mood, the atmosphere...it's just works. My 13 year old is a harsher critic and gave it an "average" rating.
License to Drive is just friggin' fun. I rewatched it with my daughter and she was surprised how enjoyable it was (she said it was "better than average").
REAL GENIUS: it's not a perfect film, by any means, but enough of it is totally enjoyable to make it work.
SHORT CIRCUIT: I know it's offensive (casting choices....Plus, Gutenberg is usually so lame, but he is OK in this film), but I think it's a great movie.
