So much of this oddly named but perfectly played dramedy feels real, from the revisits to VHS tapes in parents' basements to the way a family member's glance can trigger fight-or-flight responses.

"Do-Deca" can't always overcome the sensation that this is as much a no-budget as it is a no-holds-barred affair. But the sardonic slights and crafty insights are steadily there.

Do-Deca-Pentathlon showcases the deft way with interpersonal relationships that's making the Duplasses two of our premier chroniclers of just why it is that we can never seem to get along.

Although very funny, this film taps into a primal male competitiveness whose force outweighs reason and common sense.

Even as small movies go, it's tiny, with a budget to match. But it's got a big heart.

Do-Deca is a stripped-down examination of male relationships and identity crisis. It's as if someone picked up a bromance and shook the dumb bits out.

You begin the film thinking you have a pretty good idea where it's going, and you find out not even Jeremy and Mark really know.
