All I see is You Blake Lively, Jason Clarke, Ahna O’Reilly. Directed by Marc Forster. Rated R. Opens Friday in select theaters.

Something (aside from the blindness she’s lived with since a car accident as a child) seems off about Gina’s life from the very beginning of Marc Forster’s lethargic semi-thriller All I See Is You, but it takes nearly the entire movie for anything to come of it. Forster uses ominous sound cues, skewed camera angles and furtive looks between characters to create an atmosphere of low-level dread right away, as Gina (Blake Lively) lives with her insurance-executive husband James (Jason Clarke) in a Bangkok high-rise apartment and anticipates the surgery that may restore her sight.

Once that surgery is a success, the couple’s marriage gradually comes apart, as the newly independent Gina starts dressing more fashionably, wearing makeup and relying less on James for her daily needs. Is her husband hiding a sinister secret? Not really, although there is a half-hearted (and blatantly telegraphed) twist at what passes for the movie’s climax. Before that, the story is slow and vague, with underdeveloped hints at a ’90s-style erotic thriller or a romantic weepie.

Lively and Clarke have minimal chemistry either as lovers or as adversaries, and the supporting characters are mostly there for exposition. Forster plays with some intriguing ways to illustrate Gina’s limited sight onscreen, all blurred colors and swirling lights, but even those become repetitive and superfluous, serving to pad out a story that’s barely formed in the first place.
