A funny thing - perhaps even a flipped-turned upside down thing - happened on the way to "Focus": The world fell out of love with Will Smith. The fairly small, R-rated con movie was never going to be the blockbuster to bring Smith firmly back up to sure thing box office status. What it does do, however, is quite nicely kill about two hours in sexy, sleek and breezily enjoyable fashion - a kind of Ocean's 6 or 7.
