The Beach (the book) by Alex Garland was cool. Ex Machina was cool. Devs tries to hard to be cool.

The acting and the direction of said actors is crap. All the young 'hip' actors speak in a quiet monotone, trying to imply cool, mysterious insight. It doesn't work. And the dialogue contains too many swear words which makes the characters unrealistic. People don't speak like that.

The direction by AG in Ex Machina was very good and he achieved the 'cult' look he was after, but In Devs he again tries too hard to make every scene have the arty cult look. That results in too many drawn-out scenes.

That brings me to the length of the show - The first five episodes could have been reduced to two and the whole series done in four episodes.

My recommendation is to give it a try. If you like it, you'll love it, but if it bores you then give it a miss.
