Clueless - Blade Runner is ok but hardly worthy of the praise it gets smothered with - The Fifth Element is vastly under rated, great film.
You're half right. Both are in their way brilliant. Blade Runner is pretty much perfect and actually quite deep. Whilst I've not yet read the short story - it's on my shelf - it does clearly have a phildickian (and yes, that is a word apparently) feel about reality and what it is to be human. Looks fantastic too. Ridley's latest films also look good but are rather stupid in comparison.
Fifth Element is in comparison a lightweight film in terms of meaning and ambition, quite silly really, yet it is immensly entertaining and a joy to watch, and perfectly crafted. At the risk of being (only slightly) pretentious, I gather Luc--B was an exponent of "cinema du look" - and doesn't it look great.
I enjoyed Valerian too but it's not in the same league as 5th element.
