Cuckoo

[A] workaday psychological thriller which, although decently crafted, lacks even a scintilla of subtlety or ambition.

It's poorly plotted, deeply uninvolving tosh that makes you cringe for Grant and the estimable Tamsin Greig as his colleague and former protégé.

A centrepiece monologue from Grant on CIA experimentation shows some style, but it's too little, too late, and is rendered moot by the underwhelming climax.

An unsettling, unconventional and delicately-handled piece quite unlike anything our film industry is pumping out these days.

An alarming head-scratcher, but hopefully a blip for this still-promising creative team.

Creepy claustrophobic for a bit, it dissolves quickly into suspenseless drift - not all of it coherent.

A funny film, but not in a ha ha way.

Bracewell's lofty ambitions are clear to see in what is an obvious labour of love, but they simply don't come off in a mess of clichés and barely adequate performances.

With its unengaging characters and a plot that jacknifes inexplicably, there's little to like here. A thriller without many thrills.
