Ex Machina is one of the better surprises of 2015 with a well told story taking a subject seen many times before yet giving it that extra layer and giving us three distinguished characters each fleshed out so well.
The premise was interesting enough but the execution was pretty bad, as were some of the performances (though Alexandra Stewart was okay). I guess if you have a fascination with Dutch/German productions in the English language, with Hitchcockian-like stories, this might be worth checking out, if only for the oddball nature.
