Ben Zuk‘s “Salute to Cinema” is just another flashy collage of scene slivers. Not a hint of content or feeling or theme interrupts the nonstop so-whattitude — combustion, verve, sound and fury…roller-coaster! And it doesn’t hold a candle to Matthew Seitz’s recent assemblage. Pay a little less attention to the 4th of July sparkler aspects and a little more to what the films were actually about.
