Unconvincing in example sentence
Well...there were some great, creamy-smooth facial shots of Marlene, along with her "shocking", gender-bender outfit (plus her not-to-be-missed "transmogrification" from ape into human being); but, overall, the generally unconvincing plot and dated acting -- not to mention the less than engaging tunes coming from Miss Dietrich's "baritone" voice --did little to ensure Blonde Venus a permanent place in my mind's Pantheon of Memorable Films.
