Whereas the later "Saw" films were hampered by bloated backstory, various ostentatious agendas, and self-satisfied sadism, The Collection feels utterly unburdened by anything but its lean, fleet-footed plot.

It also has enough nutty energy and oddball touches - "The Wire's" Andre Royo shows up as a gun-toting, faux-hawk-sporting badass - that it's never boring. Dumb, gross, gratuitous, and overly familiar, sure. But never boring.
