Our post-"Bridesmaids" love affair with Kristen Wiig has been tested a few times in the choices she’s made since, but never more so than with "Welcome to Me."

‘WELCOME TO ME’ Rated: R Opens Friday

The quirky, clueless Plain Jane self-absorption that tested our patience in "Girl Most Likely" and "The Skeleton Twins" wears out its "Welcome" in this indulgent farce, which has her playing a mentally ill lottery winner.

Alice Klieg is a harmless head case, making no progress with her therapist (Tim Robbins), maintaining one lasting friendship (Linda Cardellini), taking her meds and watching "Oprah" re-reruns she has memorized.

Then she hits it big. To her, $86 million means her Winfrey-fed self-actualization mantras have paid off. She resolves to dump the doctor, skip her meds and buy time on a failing home shopping channel and emulate her idol, doing a show all about "Me."

She’ll talk about herself, compulsively, settle old scores with "re-creations" of big traumas from her limited, grudge-packed life. She’ll spend whatever it takes to realize her unfiltered, uncensored and seemingly unscripted vision.

Desperate channel owner Rich (James Marsden, on the money) takes her cash. And he bullies his sad, introverted TV pitchman brother (Wes Bentley, also good) to keep Alice in their clutches by courting her off-camera.

The channel’s production team (Joan Cusack, Jennifer Jason Leigh) are appalled. But Alice won’t be denied, and Rich won’t refuse the money.

The show is "wacky" in those cute movie mental illness meets TV-gone-wrong ways. And, as happens in such movies, she becomes a cable TV phenomenon.

Whatever screenwriter Eliot Lawrence and director Shira Piven ("Fully Loaded") were aiming for — spoofing a culture that has taken to celebrating narcissistic eccentrics, self-help hucksters and the like — gets lost in a simple and simply excessive Wiig star vehicle. Supporting players shrink into the shadows and any suggestion of a moral debate over letting this crank on the air disappears with them.

Wiig’s adorably offbeat timing, her loveable loser who doesn’t realize she’s a loser gift, is exhausted in what is essentially a "Saturday Night Live" sketch given 100 minutes of screen time.

Exhibitionists are always the last to know we’ve lost interest in their exhibition.

It’s just not that funny, not that sad and not on target, satirically. This "Welcome" isn’t nearly welcoming enough.
