couple of pet peeves i can think of:
when a supposedly ugly girl in a movie her glasses are taken off and suddenly shes gorgeous-not the best movie but an example Shes All That
2.also related when a pretty actress plays a homely character-michelle pfeffier in Frankie and Johnny
and the soon to be released movie with Charlise Theron
give the roles to the people that deserve them!
3. bad assembly line of mgm movies about songwriters
Three Little words and Till the Clouds Roll By
4. War patriotism getting in the middle of a good movie-
Dolly Sister and For me and my Gal
5. Claudette Colbert abandoing her lovable screwball persona to be the passionate patriotic housewife
6. Women in the old movies who make their way in the business world only to give it up completely for marriage-example Ella Cinders (and i know there's more)
