They're termed "hyperlink" movies.
Yeah, I liked 11:14 a lot despite it having some major flaws. Magnolia too. I guess if you're looking for intersecting character storylines, check out:
The Alejandro Gonzalez Inaritu trilogy: 21 Grams, Babel, Amores Perros
Others:
The Safety of Objects
Pulp Fiction
Short Cuts
And: didn't see it yet, but there's a new foreign film called "Gomorra" that follows the style.
To a lesser extent: Traffic and Syriana
