I found Isai a better watch than the recent big-ticket movies we’ve been subjected to. It has to do with the plot, which gradually becomes so preposterous that the sheer whatever-next factor pulls you through. After a point, the film lurches madly between psycho-thriller, Victorian melodrama (think Gaslight), horror-movie staples, and — I kid you not — a meta musing on the director’s long absence from the screen and his return to it. Whatever else, you have to hand him points for audacity. By the end, I was chuckling.
