I'm enough of a 50s-noir fan to like even the semi-noir ones that manage to draw me in against my better judgment and end up worth the viewing. This was kind of anomalous for Mickey Rooney I guess, but I thought he was perfect in the role.
I've just watched Blow-Up for the nth and perhaps last time. I suppose one either appreciates that film for a fairly innovative (and obliquely searing) critique of the times, or else one loathes it for the pretensions noticed during a first and perhaps only watch. But I couldn't quite decide, so I kept having another look at it once in awhile. And a few times I found it more than worth the watch. Now I find myself liking it a little less on each re-watch. That may even have been part of Antonioni's intent, who knows: a little joke that his critique of the times will eventually bring home the fact that all avant garde-ish times end up being experientially... boring?
