“13 Minutes” (**1/2 out of four) was a reasonably well-done melodrama set in the Midwest and showing the intersection of four different families (Thora Birch, Amy Smart, Anne Heche, Peter Facinelli, Trace Adkins, and others) when a deadly tornado touches down and forces them all to re-examine their relationships and mistakes they made in their lives. Imagine “Twister” re-made as a Robert Altman/Jonathan Demme emotional drama and that’s more-or-less what this is; not a total success (it does lag at times) but an interesting attempt at doing something new and given a definite boost by its first-rate cast. Birch stands out in an excellent performance as a single mom.
