Movies in the 50's started to suck around this time

Thanks to TCM, I've become addicted to movies from the 30's and 40's. Stellar scripts, taut direction, actors as icons, cinematography that shines, perfectly integrated music. By the 50's, the quality dips horribly. Here you have 40's superstar Barbara Stanwyck next to unappealing, one-dimensional actors Barry Sullivan and Ralph Meeker, fighting a cacophony of a score, looking more like a TV show than a film.

Not that I didn't like Jeopardy. I watched it all the way through and pulled for the husband to survive. But the whole thing reeks of cheapness and cheap thrills.
