This one is easy. It's the science fiction film that we ALL know is is rubbish but we all love it anyway.
Dum-dum-dum-dum-dum .... Flash! Ah-ah.
We should hate this movie but it's just a great romp. The stellar cast enjoy themselves hugely. The costumes are fabulous. The dialogue is cheesy, "Flash, I love you, but we only have fourteen hours to save the Earth!". And then there is that pounding Queen soundtrack.
It's a great film. Give in to the power of the dark side and watch Flash Gordon again.
