The Spanish thriller “You Are Not Me” takes its sweet, creepy time getting around to stating the obvious.

Set and shot in rural Valencia, it’s about a doctor/daughter who’s come home for the holidays, bringing her wife and Black adopted baby all the way from Brazil, only to find that she’s been pretty much displaced by this strange woman from Eastern Europe, a refugee.

Whatever allegorical points might be made about human migration, race and acceptance of the first (out) gay person in the family are bathed in gloom and the overwhelming “Rosemary’s Baby” vibe of it all.

Aitana (Roser Tapias) wanted to make this a “surprise” visit. She and her Brazilian social worker wife Gabi (Yapoena Silva) and gurgling baby João just pop in at the hacienda where Aitana grew up.

A stranger, one of some “new friends” of her parents answers the door. The family’s “You should have called” (mostly in Spanish, with English subtitles) is underscored by brain-tumor paraplegic brother Saul’s (Jorge Motos) delight, with veiled warnings about something they “weren’t invited to.”

Hearing the older folks refer to her baby as “a chocolate bon bon” is bad enough. Finding a stranger in her old bedroom rattles Aitana further. Who is this Nadia (Anna Kurikka). Why is she in my bed? Why’d you put her pictures over mine in all these frames? And what’s the deal with trimming my old wedding dress for her?

Gabi tries to roll with the punches, but Aitana veers between outrage and barely molified fury. She must insist that they pack their bags and leave five times, not including father Justo’s (Alfred Picó) brusque “I’ll drive you to a hotel” offer on their arrival.

Aitana looks for clues and hallucinates nightmare scenarios. She finds herself locked in her room, and more than once. What’s going on here, and who are all these people showing up for a Christmas Eva party that used to be just a family affair?

Tapias manages a decent rendition of a meltdown in the lead role. But Aitana’s ongoing uncertainty and slowness to act gets to be frustrating.

The worst consequence of a movie that shows its cards, blending hints of the supernatural with the Spanish adoration of all things porcine, too early is the impatience the viewer develops for “When will SHE figure it out?” and “When will THEY admit what this is all about?”

But even taking that into account, co-writers/directors “You Are Not Me (Tú no eres yo)” Marisa Crespo and Moisés Romera struggle to keep this repetive, pokey thriller on the move. They’ve teamed up for years of short films, and that might have impacted their notion of how much plot and action you really need for a 100 minute thriller.

By the time what seemed inevitable early on becomes clear, I’d almost lost interest. Not quite, but almost.
