Ensemble marriage comedy a misstep for director Lake Bell

I've never been married, but fortunately I've seen lots of movies about marriage, so I know that, like, marriage is hard, you guys.

Perhaps I'm not the target audience for the ensemble comedy “I Do … Until I Don't,” but it covers such well-worn territory it was a disappointment, given the talent involved.

Written and directed by Lake Bell, it's the follow up to her fantastic directorial debut, “In a World …” (Apparently, she loves ellipses as much as I do.)

When a favorite documentary filmmaker (Dolly Wells) espouses the notion that marriage is an outdated convention, Alice (Bell) volunteers to be a subject along with her husband, Noah (Ed Helms).

Alice soon learns this may be more than she bargained for, as her free-spirited younger sister, Fanny (Amber Heard), and her partner, Zander (Wyatt Cenac), will also be in the documentary exploring their open relationship.

An older couple named Cybil and Harvey (Mary Steenburgen and Paul Reiser) completes this look at marriage in three stages.

After the assured and unique movie voiceover comedy “In a World,” it's hard not to be disappointed with “I Do.” The territory is obviously well-worn, and while the heart is there, for the most part, the film is surprisingly light on the laughs.

Even the documentary angle, which brings a kind of anthropological aspect to marriage, feels like a watered-down “I Heart Huckabees” at times.

And it's a real shame, too, because not only is Bell immensely talented, she's got a fine cast here. Let's chalk this one up to a sophomore slump and look forward to her next project.
