Surely "Gigli" cannot be as bad as these ones ?
There are just too many other contenders to name...
"Lust. Caution" was a particular artsy fartsy waste of time despite all the awards it got.
"The Mist" still stands as an over acted, poorly scripted, desperate Hollywood attempt at adapting a Stephen King's novel into a horror movie.
I'm still owed about 2 hours of my life watching "Marley & Me" which (for reasons I can only explain by biology) seems to be ranked as a classic tearjerker by most women I know...
Dog is born -> Dog acts silly -> Dog dies... What the f*** is there a need for a movie to tell that ?
