Steven Soderbergh has been telling interviewers that he’s planning to take a sabbatical from filmmaking because he has lost his inspiration. His lack of interest is palpable in <span class="italic">Haywire</span>, a rote exercise in action filmmaking that is sleek and polished and instantly evaporates from memory.
